UNLABELLED: Limosilactobacillus reuteri, a probiotic microbe instrumental to human health and sustainable food production, adapts to diverse environmental shifts via dynamic gene expression. We applied the independent component analysis (ICA) to 117 RNA-seq data sets to decode its transcriptional regulatory network (TRN), identifying 35 distinct signals that modulate specific gene sets. Our findings indicate that the ICA provides a qualitative advancement and captures nuanced relationships within gene clusters that other methods may miss. This study uncovers the fundamental properties of L. reuteris TRN and deepens our understanding of its arginine metabolism and the co-regulation of riboflavin metabolism and fatty acid conversion. It also sheds light on conditions that regulate genes within a specific biosynthetic gene cluster and allows for the speculation of the potential role of isoprenoid biosynthesis in L. reuteris adaptive response to environmental changes. By integrating transcriptomics and machine learning, we provide a system-level understanding of L. reuteris response mechanism to environmental fluctuations, thus setting the stage for modeling the probiotic transcriptome for applications in microbial food production. IMPORTANCE: We have studied Limosilactobacillus reuteri, a beneficial probiotic microbe that plays a significant role in our health and production of sustainable foods, a type of foods that are nutritionally dense and healthier and have low-carbon emissions compared to traditional foods. Similar to how humans adapt their lifestyles to different environments, this microbe adjusts its behavior by modulating the expression of genes. We applied machine learning to analyze large-scale data sets on how these genes behave across diverse conditions. From this, we identified 35 unique patterns demonstrating how L. reuteri adjusts its genes based on 50 unique environmental conditions (such as various sugars, salts, microbial cocultures, human milk, and fruit juice). This research helps us understand better how L. reuteri functions, especially in processes like breaking down certain nutrients and adapting to stressful changes. More importantly, with our findings, we become closer to using this knowledge to improve how we produce more sustainable and healthier foods with the help of microbes.

- Abstract
Background: The rate of NAFLD in the general population is estimated to be 25.2%. NAFLD is affected by lifestyle, diet, and inflammation. In this study, the use of probiotics, prebiotics, and synbiotics was aimed to modulate the circadian clock in the liver and improve metabolic disorder through the gut–liver axis. Methods: Six-week-old, healthy, 43 Wistar albino rats were included in the study and their average weight was determined as 140.50 g (95.00–177.00) at the beginning of the study. Before the study, the rats were randomly divided into 5 groups, 8 animals were placed in the 1st, 3rd, 4th, and 5th groups and 11 animals were placed in the 2nd group. Rats in group 1 were fed standard food for 13 weeks. Rats in the 2nd, 3rd, 4th, and 5th groups were fed with 10% fructose water during the 1-week adaptation period and then 20% fructose water. After the 7th week, probiotic treatment (2 × 109 CFU/ml Lactobacillus rhamnosus GG) was administered to rats in group 3rd via gavage for 6 weeks, and prebiotic treatment was administered to rats in group 4th with feed containing 10% grape seed extract. Rats in the 5th group were given a feed consisting of 10% grape seed extract and 2 × 109 CFU/ml Lactobacillus rhamnosus GG via gavage. Results: It was determined that the use of prebiotics as a treatment option in fatty liver had a more positive effect on glucose, ALT, melatonin, and ZO-1 values. In addition, it was observed that synbiotic use had more positive effects on histopathological findings, NAS score, and the expression level of circadian clock genes. While there was no significant difference between the mRNA levels of circadian clock genes, it was observed that gene expression levels increased with fructose consumption and decreased especially with synbiotic treatment. Conclusion: It has been observed that fructose modulates the circadian rhythm by affecting some biochemical and genomic pathways as a result of synbiotic use in order to prevent the negative effects of fructose on fatty liver.

- Abstract
Background: The quest for candidate probiotics and prebiotics to develop novel synbiotics for sustainable and profitable fish farming remains a major focus for various stakeholders. In this study, we examined the effects of combining two fungal probiotics, Saccharomyces cerevisiae and Aspergillus niger with extracts of Jerusalem artichoke and white button mushroom to develop a synbiotic formulation to improve the growth and health status of zebrafish (Danio rerio). An initial in vitro study determined the most effective synbiotic combination, which was then tested in a 60-day in vivo nutritional trial using zebrafish (80 ± 1.0 mg) as a model animal. Four experimental diets were prepared: a control diet (basal diet), a prebiotic diet with 100% selected mushroom extract, a probiotic diet with 107 CFU of S. cerevisiae/g of diet, and a synbiotic diet with 107 CFU of S. cerevisiae/g of diet and 100% mushroom extract. As readouts, growth performance, survival, digestive enzyme activity and innate immune responses were evaluated. Results: In vitro results showed that the S. cerevisiae cultured in a medium containing 100% mushroom extract exhibited the maximum specific growth rate and shortest doubling time. In the in vivo test with zebrafish, feeding them with a synbiotic diet, developed with S. cerevisiae and mushroom extract, led to a significant improvement in the growth performance of zebrafish (P < 0.05). The group of zebrafish fed with the synbiotic diet showed significantly higher levels of digestive enzyme activity and immune responses compared to the control group (P < 0.05). Conclusion: Taken together, these results indicated that the combination of S. cerevisiae and mushroom extract forms an effective synbiotic, capable of enhancing growth performance and immune response in zebrafish.

- Abstract
Introduction: Depression and anxiety are pervasive mental health disorders with substantial global burdens. Probiotics, live microorganisms known for their health benefits, have emerged as a potential therapeutic intervention for these conditions. This systematic review and meta-analysis aim to evaluate the strain-specific effects of probiotics on relieving depressive and anxiety symptoms while elucidating underlying mechanisms. Methods: EMBASE, Cochrane CENTRAL and PubMed/Medline were systematically queried to identify studies released until May 15, 2024. Randomized Controlled Trials (RCTs) that employed standardized assessment tools for depression and anxiety namely Beck Depression Inventory (BDI), Hamilton Depression Rating Scale (HAMD), Depression Anxiety Stress Scales (DASS), or Montgomery-Asberg Depression Rating Scale (MADRS) were included. Results: 12 RCTs involving 707 participants were included. Seven RCTs utilizing the BDI questionnaire demonstrated a significant decrease in depressive symptoms favoring probiotics containing strains such as Lactobacillus acidophilus, Lactobacillus paracasei, Lactobacillus casei, Lactobacillus plantarum, Lactobacillus salivarius, Bifidobacterium bifidum, Bifidobacterium lactis, Bifidobacterium breve, and Bifidobacterium longum (MD: -2.69, CI95%: -4.22/-1.16, p value: 0.00). Conversely, RCTs using HAMD showed a non-significant reduction in depressive symptoms (MD: -1.40, CI95%: -3.29/0.48, p value: 0.14). RCTs employing DASS and MADRS scales also showed no significant differences. Conclusion: This meta-analysis offers valuable insights into the strain-specific effects of probiotics containing Lactobacillus and Bifidobacterium species on depressive and anxiety symptoms. While our findings suggest a significant reduction in depressive symptoms based on the BDI scale favoring probiotics, the lack of significant effects observed on the HAMD, DASS, and MADRS scales underscores the complexity inherent in these conditions. It is imperative to acknowledge the mixed results across different measurement scales, indicating the need for cautious interpretation. Therefore, we advocate for a nuanced understanding of probiotics' impacts on various dimensions of mood, emphasizing the necessity for further research. [ABSTRACT FROM AUTHOR]

ABSTRACT Background Methods Results Conclusion The complex ecosystem of the skin microbiome is essential for skin health by acting as a primary defense against infections, regulating immune responses, and maintaining barrier integrity. This literature review aims to consolidate existing information on the skin microbiome, focusing on its composition, functionality, importance, and its impact on skin aging.An exhaustive exploration of scholarly literature was performed utilizing electronic databases including PubMed, Google Scholar, and ResearchGate, focusing on studies published between 2011 and 2024. Keywords included “skin microbiome,” “skin microbiota,” and “aging skin.” Studies involving human subjects that focused on the skin microbiome's relationship with skin health were included. Out of 100 initially identified studies, 70 met the inclusion criteria and were reviewed.Studies showed that aging is associated with a reduction in the variety of microorganisms of the skin microbiome, leading to an increased susceptibility to skin conditions. Consequently, this underlines the interest in bacteriotherapy, mainly topical probiotics, to reinforce the skin microbiome in older adults, suggesting improvements in skin health and a reduction in age‐related skin conditions. Further exploration is needed into the microbiome's role in skin health and the development of innovative, microbe‐based skincare products. Biotherapeutic approaches, including the use of phages, endolysins, probiotics, prebiotics, postbiotics, and microbiome transplantation, can restore balance and enhance skin health. This article also addresses regulatory standards in the EU and the USA that ensure the safety and effectiveness of microbial skincare products.This review underscores the need to advance research on the skin microbiome's role in cosmetic enhancements and tailored skincare solutions, highlighting a great interest in leveraging microbial communities for dermatological benefits.

AbstractProbiotic lactic acid bacteria (LAB) must undergo three key stages of testing, including food processing, storage, and gastrointestinal tract environment, their beneficial effects could exert. The biofilm formation of probiotic LAB is helpful for improving their stress resistances, survival rates, and colonization abilities under adverse environmental conditions, laying an important foundation for their probiotic effects. In this review, the formation process, the composition and function of basic components of probiotic LAB biofilm have been summarized. This review focuses on the regulatory mechanism of probiotic LAB biofilm formation. In addition, the characteristics and related mechanisms of probiotics in biofilm state have been analyzed to guide the application of probiotic LAB biofilms in the field of health and food. The biofilm formation of LAB is an extremely complex process involving multiple regulatory factors. Besides quorum sensing (QS), other regulatory factors are not yet fully understood. The probiotic LAB in biofilm state exhibit superior survival rate, adhesion performance, and immunomodulation ability, attribute to various metabolic processes, including stress response, exopolysaccharide (EPS) metabolism, amino acid and protein metabolisms, etc. The understanding about regulatory mechanism of biofilm formation of different probiotic species and strains will accelerate the development and application of probiotics products.

Association between metabolic syndrome (MetS) and oxidative stress has been shown in numerous studies. It has been shown that probiotics could be the effective treatment strategy in improving oxidative stress. This study aimed to determine the effects of a new developed synbiotic yogurt on oxidative stress status in adults with MetS. Forty-four individuals were assigned into two groups and given 300 g of synbiotic yogurt containing Lactobacillus plantarum, Lactobacillus pentosus, and Chloromyces marcosianos yeast or regular yogurt for 12 weeks in this randomized, placebo-controlled clinical trial. Before and after the intervention, biochemical parameters were assessed. Daily consumption of synbiotic yogurt in adults with MetS showed a statistically significant improvement in the level of glutathione peroxidase (p = 0.01) and total oxidant status (p = 0.006) compared to the regular yogurt. Total Antioxidant Capacity and superoxide dismutase levels increased significantly (p = 0.002 and p = 0.02, respectively) in the intervention group compared to the baseline levels. In adults with MetS, daily consumption of the synbiotic yogurt containing native strains of Lactobacillus plantarum, Lactobacillus pentosus, and Chloromyces marcosianos yeast for 12 weeks was associated with improvements in oxidative stress status.

Sea buckthorn has lipid‐lowering properties and is widely used in the development of functional foods. In this study, a probiotic (
Lactobacillus plantarum , Lp10211) with cholesterol‐lowering potential and acid and bile salt resistant was screened for the fermentation of sea buckthorn juice. Changes in the active ingredients, such as sugars and phenolics, before and after fermentation, as well as their in vitro lipid‐lowering activities, were compared. The contents of reducing and total sugars decreased substantially after fermentation. Lp10211 primarily utilized fructose for growth and reproduction, with a utilization rate of 76.9%. The phenolic compound content of sea buckthorn juice increased by 37.06% after fermentation and protected the phenolic components from degradation (protocatechuic andp ‐coumaric acids) and produced new polyphenol (shikimic acid). Enhanced inhibition of pancreatic lipase activity (95.42%) and cholesterol micellar solubility (59.15%) was evident. The antioxidant properties of the fermentation broth were improved. Notably, Lp10211 preserved the color and reversed browning in sea buckthorn juice. The collective findings indicate that fermentation of sea buckthorn juice by Lp10211 may enhance the functional components and lipid‐lowering activity of sea buckthorn, which may provide a new approach for the development of lipid‐lowering foods.

Background: Metabolomics is the study of metabolites in cells, tissues, live organisms, and biological fluids to elucidate their composition and possible roles. Metabolomics and its biomarkers have emerged as a powerful tool for evaluating the efficacy of probiotics in various pathological conditions, including toxicological settings. This review explores the use of metabolomics-based markers to assess the safety and efficacy of probiotics in toxicological settings. Result: This review aims to determine biomarkers for measuring the effectiveness of probiotic therapies in toxicological contexts based on exposure, effects, susceptibility, prognostic, and therapeutic biomarkers. In this study, 1979 articles were systematically searched in PubMed (PM), Scopus (Sc), Google Scholar (GS), and Web of Science (WOS) between the years 2013 and 2023 inclusive using keywords, inclusion, and exclusion criteria. The result showed that 1439 human samples were used from 2013 to 2023 publications with the UK having the highest number of publications, data, and sample types in 2023. Again, the result showed most of the publications are on susceptibility-based biomarkers. Conclusion: Metabolomics-based biomarkers may provide insight into metabolism-related alterations related to probiotic therapies while clarifying their biological mechanisms, especially in toxicology enabling specific probiotic therapy.

Purpose: This study aimed to determine the effect of the probiotic Saccharomyces boulardii (S. boulardii) in patients with knee osteoarthritis (KOA). Methods: In this study, 70 patients with KOA were recruited via outpatient clinics between 2020 and 2021 and randomly assigned to receive probiotics or placebo supplements for 12 weeks. The primary outcome was a change in pain intensity according to the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) pain score. Results: Sixty-three patients completed the trial. A linear mixed analysis of covariance (ANCOVA) model analysis showed that probiotic was better than placebo in decreasing the pain intensity measured by visual analogue scale (VAS) [−2.11 (−2.59, −1.62) in probiotic group and −0.90 (−1.32, −0.48) in placebo group, p = 0.002] and WOMAC pain score [−3.57 (−4.66, −2.49) in probiotic group and −1.43 (−2.33, −0.53) in placebo group, p < 0.001]. The daily intake of acetaminophen for pain management significantly decreased in the probiotic group [−267.18 (−400.47, −133.89) mg, p < 0.001] that was significantly better than placebo (p = 0.006). Probiotic significantly decreased the serum levels of high-sensitivity C-reactive protein (hs-CRP) inflammatory index [−2.72 (−3.24, −2.20) µg/ml] and malondialdehyde (MDA) oxidative stress index [−1.61 (−2.11, −1.11) nmol/ml] compared to the placebo (p = 0.002 and p < 0.001, respectively). Probiotic was better than placebo in increasing the scores of role disorder due to physical health (p = 0.023), pain (p = 0.048) and physical health (p = 0.031). Conclusion: Probiotic S. boulardii supplementation in patients with KOA significantly improved pain intensity, some dimensions of QoL, and inflammatory and oxidative stress biomarkers with no severe side effects.

Objective: To compare the outcomes associated with the use of probiotics, prebiotics, and synbiotics for the treatment of chronic constipation in adults. Methods: We searched eight electronic databases from database inception to July 11, 2023, to identify randomized controlled trials (RCTs) that report efficacy and safety for the treatment of chronic constipation. The risk of bias in the included RCTs was evaluated according to the Cochrane tool, and the certainty of the evidence was assessed using the Confidence in Network Meta-Analysis framework. The analysis was conducted using R version 4.3.0. Results: Out of the 37 RCTs, a total of 21 different types of interventions were reported, involving 3,903 patients. This NMA demonstrated that both prebiotics and synbiotics resulted in an increase in frequency of stool movements per week. Compared to placebo, lactulose (Mean difference [MD] = 3.39, 95% Confdence interval [CI] [1.13, 5.65], moderate certainty), mix2 (consisting of Lactulose and Bacillus coagulans) (MD = 3.63, 95% CI [1.37, 5.89], moderate certainty), mix6 (consisting of Lactulose and Bifidobacterium coagulans) (MD = 4.30, 95% CI [1.04, 7.54], low certainty), and mix7 (consisting of Lactulose, Bifidobacterium subtilis, and Enterococcus faecium) (MD = 4.58, 95% CI [1.35, 7.78], moderate certainty) exhibited a significant effect. Notably, mix7 demonstrated the highest probability of being the most effective intervention (94.8%). Furthermore, when compared to L. plantarum, four probiotics and two synbiotics showed significant advantages in the Patient Assessment of Constipation Symptoms (PAC-SYM) score. L. reuteri (MD = -13.74, 95% CI [-22.20, -4.66], very low certainty) exhibited a significant effect in improving the Patient Assessment of Constipation Quality of Life (PAC-QoL) score. In terms of safety, there were no statistically significant differences between the intervention and control groups in all adverse event analyses. Conclusions: Moderate to very low evidence supports the use of lactulose and synbiotics to increase the number of weekly stool movements in patients, particularly highlighting the significant impact of synbiotics in increasing the number of weekly stool movements in patients with constipation. The use of L. paracasei showed improvements in PAC-SYM scores, while L. reuteri demonstrated enhancements in PAC-QoL scores. [ABSTRACT FROM AUTHOR]

Objective: In this study, the protective effects of native Iranian probiotics (Lactobacillus rhamnosus, Lactobacillus casei and Lactobacillus holoticus) on lead acetate (PbAc)-induced toxicity in the kidney of male rats were investigated using biochemical, molecular and histopathological approaches. Materials and Methods: Twenty-one male Wistar rats were divided into three groups (n=7/group), including controls, PbAc recipient (10 mg/kg) and PbAc recipient (10 mg/kg) + probiotic mixture (109 CFU). PbAc and probiotics were gavage in the groups. On the 31st day, blood samples were used to measure serum concentrations of creatinine (Cr), blood urea nitrogen (BUN), sodium, total protein and potassium. Rats were dissected and renal tissues apoptotic and inflammatory genes were evaluated. Results: PbAc increased serum concentrations of Cr, sodium, and urea, and decreased total protein and potassium, while it enhanced interleukine-6 (IL-6) and tumor necrosis factor -α (TNF- α) gene expression in kidney tissue compared to the control group. Probiotic mixture decreased Cr, BUN, and malondialdehyde and increased activity of catalase and superoxide dismutase enzymes in kidney tissue. Conclusion: The results of the study showed that the native Iranian probiotics mixture can be used to protect the function and structure of the kidneys against toxic and oxidative damage induced by PbAc.

Probiotic bacteria continue to receive increasing attention in the food and feed industries. However, the production of Bifidobacterium and Lactobacillus at an industrial scale is challenging because of specific nutrient requirements and conditions, which are complicated and costly. We developed low-cost culture media by modifying the carbon and nitrogen sources for Bifidobacterium animalis subsp. lactis KMP-H9-01 and Lactobacillus reuteri KMP-P4-S03 from available food grade components. Sucrose (15 g/l) was selected as a suitable carbon source for both strains because it was the most economic and facilitated bacterial growth that was equal to that of glucose. The Bifidobacterium strain required beef extract as a nitrogen source to multiply. The fermentation of both strains using the modified media formula in 5-L and 50-L bioreactors showed that the highest cell counts of L. reuteri and B. animalis subsp. lactis were 9 and 9.8 log CFU/ml after 12–15 h, respectively. The concentration (g/l) ratio between lactate and acetate obtained from B. animalis subsp. lactis was 7:7.4 at 12 h and 11.4:10.6 at 40 h; the ratio was similar at both time points (6.9: 1.1) for L. reuteri. Thus, this economically modified food-grade medium for the large-scale fermentation of two probiotic bacteria was efficient. [ABSTRACT FROM AUTHOR]

Extensive antibiotic use in the poultry industry has given rise to concerns of the proliferation and potential zoonotic transmission of antimicrobial-resistant pathogens. To mitigate the extent of antibiotic dosing, probiotics have been proposed as an alternate means of enhancing chick immune function by boosting host defense peptide (HDP) production. This study measured chick immune response to in ovo supplementation of a commercial poultry probiotic when subsequently exposed to a mimicked viral threat using polyinosinic-polycytidylic acid (poly(I:C)). To assess systemic immune responses to these conditions, real-time PCR was conducted to measure changes in expression of five immune-related genes in the spleen: TLR-3, AvBD-2, IFN-a, IFN-b, and IL-6. The chicks that received only the probiotic treatment saw a downregulation of TLR-3 (p50.0013) and an upregulation of AvBD-2 (p50.0105). The expression of IL-6 tended towards downregulation (p50.06) with a potential interaction between the probiotic and poly(I:C) treatments (p50.0794). Upregulation of AvBD-2 indicates a higher basal output of the chick's innate immune system upon early exposure to probiotics. These results suggest that enhanced systemic immune response in chicks can be achieved through early application of probiotics and is occurring through immunomodulation pathways that have not been fully elucidated.

In the present study the effects of probiotic bacteria on textural and sensorial attributes of sour cream was considered. The cream samples were incorporated by three probiotic bacteria including Lactobacillus casei, L.helveticus and Bifidobacterium lactis as single culture. The pH values, viability of probiotics, textural and sensorial features were evaluated at the time of 1, 15 and 30 days of storage. The mentioned parameters were compared to the control cream sample. The pH values, probiotic survival, textural (firmness, consistency and adhesiveness) and sensorial (off-note, cohesiveness, creaminess, odor, sourness, metallic after taste, taste) properties of cultured cream samples differed depending on the used cultures. Totally, incorporation of probiotic bacteria into sour cream can result in manufacturing of a new healthy product in the market of dairy products. [ABSTRACT FROM AUTHOR]

LACTOBACILLUS reuteri , *BREAST cancer , *CADMIUM , *CADMIUM chloride , *CANCER prevention - Abstract
The current study aimed to investigate the role of probiotic Lactobacillus reuteri for the treatment and prevention of breast cancer. Breast cancer was induced by using Cadmium Chloride (Cd) (2 mg/kg) in group II. Tamoxifen was administered to group III. Group IV was treated with Lactobacillus reuteri. Group V was treated with Cd for one month and divided into three subgroups including VA, VB, and VC which were treated with tamoxifen, Lactobacillus reuteri , and tamoxifen + Lactobacillus reuteri , respectively. Significantly higher levels of TNF-α (40.9 ± 4.2 pg/mL), IL-6 (28.0 ± 1.5 pg/mL), IL-10 (60.2 ± 2.0 pg/mL), IFN-γ (60.2 ± 2.0 pg/mL), ALAT (167.2 ± 6.2 U/l), ASAT (451.6 ± 13.9 U/l), and MDA (553.8 ± 19.6 U/l) was observed in Cd group. In comparison, significantly lower levels of TNF-α (18.0 ± 1.1 pg/mL), IL-6 (9.4 ± 0.4 pg/mL), IL-10 (20.8 ± 1.1 pg/mL), IFN-γ (20.8 ± 1.1 pg/mL), ALAT (85.2 ± 3.6 U/l), ASAT (185 ± 6.9 U/l), and MDA (246.0 ± 7.5 U/l) were observed in group Cd + Tam + LR. Liver histopathology of the Cd group showed hemorrhage and ductal aberrations. However, mild inflammation and healthier branched ducts were observed in treatment groups. Furthermore, the renal control group showed normal glomerular tufts, chronic inflammation from the Cd group, and relatively healthier glomerulus with mild inflammation in treatment groups. Hence, the preventive and anticancerous role of probiotic Lactobacillus reuteri is endorsed by the findings of the current study. [ABSTRACT FROM AUTHOR]

Rationale: Probiotics have beneficial effects on the nervous system by modulating the gut-brain axis. Additionally, vitamin D supplementation presents a potential way for ameliorating neuropsychological disorders, particularly in regions with a high prevalence of vitamin D deficiency. Objectives: The current clinical trial aimed to investigate the role of co-administered supplementation of probiotics and Vitamin D on the different inflammatory aspects of patients with Parkinson's disease. Methods: Forty-six patients with PD were recruited From the Functional Neurosurgery Research Center, Tehran, Iran. These patients were randomly allocated to one of the two treatment groups: Group A, who received probiotic/vitamin D supplements (n = 23), and Group B who received placebo capsules (n = 23) for 12 weeks. As primary outcomes, Interferon-Gamma (IFN-γ), interleukin 1 beta (IL-1β), IL-6, IL-10, Tumor Necrosis Factor-Alpha (TNF-α), total antioxidant capacity (TAC), and malondialdehyde (MDA) in serum were evaluated at the baseline and the end of the trial. Moreover, Additional questionnaire-based factors including gastrointestinal symptom rating scale (GSRS), Beck Anxiety Inventory (BAI), and Unified Parkinson's Disease Rating Scale (UPDRS) were evaluated. Results: Our findings demonstrated that the consumption of probiotic/vitamin D supplements leads to a significant decrease in IL-1β, INF-γ, IL-6, and MDA levels, while showing a significant increase in IL-10 and TAC levels compared to the placebo group (P < 0.05). Additionally, it leads to a significant decrease in the disease severity, anxiety, and gastrointestinal problems in PD patients in comparison to the placebo group (P < 0.05). Conclusions: Given the acknowledged role of inflammation in the pathogenesis of Parkinson's disease on one hand, and the recognized anti-inflammatory and antioxidant effects associated with probiotics and vitamin D on the other hand, the concurrent administration of probiotics and vitamin D supplements emerges as a promising and potentially effective treatment option for individuals with PD.

- Abstract
Given the epidemic proportions of type 2 diabetes mellitus (T2DM) globally, it's crucial to comprehensively understand the factors influencing its management. The gut microbiome, known for its influence on various aspects of health, has emerged as a potential regulator of blood pressure in individuals with T2DM. This umbrella review aimed to consolidate the findings of existing meta-analyses investigating the impact of gut microbiome modulation on systolic and diastolic blood pressure in T2DM patients. Adhering to the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines, we systematically searched PubMed, Scopus, and Web of Science databases from inception to July 2023. Quality assessment was performed using the AMSTAR2 and GRADE checklists. Statistical analyses were conducted using Comprehensive Meta-Analysis (CMA) version 3. A total of 6 meta-analyses meeting the inclusion criteria were included. The results revealed a significant association between microbial modulation and diastolic blood pressure (SMD: −0.133; 95% CI: −0.219 to −0.048; P = 0.002). However, the effect of gut microbial modulation on systolic blood pressure did not reach statistical significance (SMD: −0.077; 95% CI: −0.162 to 0.009; P = 0.078). This study found that modulating the gut microbiome had a statistically significant impact on diastolic blood pressure in individuals with type 2 diabetes mellitus (T2DM). However, no significant effect was observed on systolic blood pressure. While high-quality meta-analyses reported favorable outcomes, caution is warranted due to the low clinical importance, diversity in study populations, and variations in interventions. • Emphasizing the importance of blood pressure control among patients with T2DM. • Introducing gut microbiome therapy as a novel treatment for T2DM.

- Abstract
A bacterial disease, flacherie, which is more prevalent in silkworms causes heavy loss to the silk industry. This disease is typified by the flaccid condition of the affected larvae and caused by bacteria and non-occluded viruses individually and in combination. It is one of the major contributing factors to cocoon crop loss in India. The present work aims to isolate Lactic acid bacteria (LAB) residing in the gut of Eri silkworm and decipher its antagonistic activity against selected pathogens of silkworm which are responsible for causing flacherie in silkworm. Lactic acid bacteria Ligilactobacillus salivarius was isolated from the midgut of Eri silkworm and it exhibited antibacterial activity against Staphylococcus aureus, Proteus vulgaris and Bacillus thuringiensis. Other than preventive measures, no remedial measure, so far, have been developed to check the infection and further spread of the disease. In this context, the present study reveals the role of LAB residing in the gut of Eri silkworm and its essential role in formulating probiotic for Eri culture. [ABSTRACT FROM AUTHOR]

- Abstract
Two probiotics were evaluated for their impact on neutral detergent fiber (NDF) and acid detergent fiber (ADF) as well as in vitro dry matter disappearance (DMD) of palm kernel cake (PKC), as a source of dietary protein and/or energy for ruminants. The treatments were four different rations: CS (control), PS (PKC as source of energy), P (PKC as source of energy and protein), and PC; two commercial probiotics formulas (ZAD and ICEC-Trol) were applied with four applications (control: without probiotic, Z: ZAD, ZI: combination of ZAD + ICEC-Trol, and I: ICEC-Trol). Using Cornell Net Carbohydrate and Protein System (CNCPS) v6.5, the experimental diets' chemical analysis and fermentability were assessed. Adding the ZAD + ICEC and ICEC was improved (P < 0.05) DM disappearance (15%), NDF digestibility (14%), and ADF digestibility (26%). Using the CNCPS indicated that PS, P, and PC rations were higher in NDF than CS ration by about 28%, and CS and PC rations were higher in NSC, NFC, and total carbohydrate (CHO) by 34, 33, and 9% respectively more than PS and P rations. CS and PC rations occurred improvement in fermentability in organic matter, total carbohydrate, and starch by 19.5, 18.5, and 16.5%, respectively. In conclusion, using probiotics with PKC resulted in a greater elimination of dry matter disappearance and improved NDF and ADF degradation, and feeding ruminants palm kernel cake as a source of protein or energy and supplementing their diets with probiotics.

Purpose: Weight regain after metabolic bariatric surgery is a common problem. Food addiction is an eating disorder that can be one of the reasons for weight regain in these patients. This study aimed to evaluate the effects of probiotic supplementation with a weight loss program and cognitive behavioral therapy (CBT) on anthropometric measures, eating behavior, food addiction, and related hormone levels, in patients with food addiction and weight regain after metabolic bariatric surgery. Materials and Methods: This randomized, triple-blind, placebo-controlled clinical trial was conducted on patients with food addiction and weight regain after metabolic bariatric surgery. Participants (n = 50) received a weight loss program and CBT plus probiotic, or placebo for 12 weeks. Then, anthropometric measurements, biochemical markers, eating behavior, and food addiction were assessed. Results: Weight and body mass index (BMI) decreased significantly in the probiotic group compared to placebo (p = 0.008, p = 0.001, respectively). Fat mass was significantly decreased in the probiotic group (p < 0.001). Moreover, a significant improvement was observed in the probiotic group's eating behavior and food addiction compared to the placebo group (p < 0.001). Serum levels of leptin decreased significantly (p = 0.02), and oxytocin serum levels increased significantly (p = 0.008) in the probiotic group compared to the placebo group. Conclusion: Adding probiotic supplements to the weight loss program and CBT is superior to the weight loss program and CBT alone in improving weight loss, eating behavior, and food addiction in patients with food addiction and weight regain after metabolic bariatric surgery.

This study aimed to diagnose the ability of two probiotic strains isolated from Siahmazgi cheese to reduce the concentration of aflatoxin M1 (AFM1), which was able to reduce it up to 50%. Two strains of Lactobacillus isolated from local Siahmazgi cheese, were inoculated into raw milk containing 10 ng/mL AFM1. AFM1 levels were assessed by HPLC at 0, 24, 48 and 72 h. Also, for the assessment of the possible reduction of AFM1 by non-viable bacterial cells, heat treatment was applied in milk. In general, significant differences were observed between the control group and AFM1 contaminated milk samples containing probiotics during 72 h of refrigeration (p < 0.05). In the presence of Lactobacillus brevis, Lactobacillus plantarum and mixture probiotics, the concentrations of AFM1 ranged from 0.102 ± 0.004 ng/mL to 0.052 ± 0.002 ng/mL, 0.114 ± 0.002 ng/mL to 0.074 ± 0.003 ng/mL and 0.108 ± 0.003 ng/mL to 0.065 ± 0.002 ng/mL, respectively. Also, in the heated group, just a decrease was observed in the first 24 h. The results showed that native Iranian strains of Lactobacillus have good potential in reducing AFM1 in milk. The time factor is effective in reducing AFM1 by living bacterial cells. [ABSTRACT FROM AUTHOR]

Dietary patterns play an important role in regards to the modulation and control of the gut microbiome composition and function. The interaction between diet and microbiota plays an important role in order to maintain intestinal homeostasis, which ultimately affect the host's health. Diet directly impacts the microbes that inhabit the gastrointestinal tract (GIT), which then contributes to the production of secondary metabolites, such as short‐chain fatty acids, neurotransmitters, and antimicrobial peptides. Dietary consumption with genetically modified probiotics can be the best vaccine delivery vector and protect cells from various illnesses. A holistic approach to disease prevention, treatment, and management takes these intrinsically linked diet‐microbes, microbe–microbe interactions, and microbe–host interactions into account. Dietary components, such as fiber can modulate beneficial gut microbiota, and they have resulting ameliorative effects against metabolic disorders. Medical interventions, such as antibiotic drugs can conversely have detrimental effects on gut microbiota by disputing the balance between Bacteroides and firmicute, which contribute to continuing disease states. We summarize the known effects of various dietary components, such as fibers, carbohydrates, fatty acids, vitamins, minerals, proteins, phenolic acids, and antibiotics on the composition of the gut microbiota in this article in addition to the beneficial effect of genetically modified probiotics and consequentially their role in regards to shaping human health. © 2024 The Authors.

AbstractEmerging evidence suggests that bone turnover is influenced by the gut microbiome through critical bone signaling pathways. The purpose of this scoping review is to examine prebiotic, probiotic, and synbiotic interventions on bone outcomes in humans across the lifespan. PubMed, Scopus, and EBSCOhost were searched until January 2023 to identify clinical trials examining bone mineral density (BMD) or bone mineral content (BMC) with gut microbiome interventions. Of three prebiotic interventions, one reported higher areal BMD (aBMD) in adolescents. In two studies in postmenopausal women, no changes in aBMD were observed despite decreased biomarkers of bone resorption. Probiotic interventions in perimenopausal or postmenopausal women demonstrated increased aBMD or attenuated bone loss in various bone regions. All studies observed attenuated bone loss (
n = 4) or increased aBMD (n = 1). One study assessed a synbiotic intervention on aBMD and observed decreased biomarkers of bone resorption but no changes in aBMD. Results suggest potential for microbiome-targeted therapies (prebiotics, probiotics and synbiotics) to attenuate bone loss. However, changes in biomarkers of bone turnover were not always accompanied by changes in bone mineralization. Future studies should utilize longer duration interventions to investigate the influence of prebiotic, probiotic, and synbiotic interventions across diverse age, sex, and ethnic cohorts.

Summary The rat's model evaluated the function of sprouted beans enriched with probiotic Lactiplantibacillus plantarum 299v in alleviating dyslipidaemia, inflammation and disturbed redox homeostasis caused by a high‐lard diet. Sprouted beans improved the total antioxidant capacity of serum and liver, regardless of whether the feeds had a higher content of low‐molecular antioxidants or were additionally enriched with probiotics. The reduction of inflammation (lowered level of C‐reactive protein) and restoration of triglycerides and total cholesterol to the levels recorded in the control group (AIN‐93M) were especially observed in the group supplemented with the control adzuki bean. Introducing sprouted legumes (both the control and probiotic‐rich) improved microbiota activity affected by a high‐lard diet. The highest, desirable reduction of urease (by 80%) and tryptophanase (by 78%) activity was found in the groups fed with probiotic‐rich adzuki and mung bean sprouts respectively. Sprouted beans improve the metabolism of individuals subjected to a diet with an increased fat‐to‐carbohydrate energy ratio, especially concerning oxidative stress injury and microbiota activity.

GUT microbiome ,BACTERIAL metabolism ,DYSBIOSIS ,HOMEOSTASIS ,PROBIOTICS - Abstract
Millions of microorganisms make up the complex microbial ecosystem found in the human gut. The immune system's interaction with the gut microbiota is essential for preventing inflammation and maintaining intestinal homeostasis. Numerous metabolic products that can cross-talk between immune cells and the gut epithelium are metabolized by the gut microbiota. Traumatic injury elicits a great and multifaceted immune response in the minutes after the initial offense, containing simultaneous pro- and anti-inflammatory responses. The development of innovative therapies that improve patient outcomes depends on the gut microbiota and immunological responses to trauma. The altered makeup of gut microbes, or gut dysbiosis, can also dysregulate immunological responses, resulting in inflammation. Major human diseases may become more common as a result of chronic dysbiosis and the translocation of bacteria and the products of their metabolism beyond the mucosal barrier. In this review, we briefly summarize the interactions between the gut microbiota and the immune system and human disease and their therapeutic probiotic formulations. We also discuss the immune response to traumatic injury. [ABSTRACT FROM AUTHOR]

Introduction: Probiotics have been recognized for their various biological activities, including antioxidant and anti-inflammatory properties. This study investigates the therapeutic effect of a novel probiotic formula, BLLL, consisting of Bifidobacterium breve, Lactobacillus plantarum, Lactobacillus paracasei, and Lactobacillus helveticus, on chronic stress-induced depressionlike behaviors in mice. Methods: The BLLL formula or phosphate-buffered saline (PBS) was given orally at a dose of 2, 4, or 8 x 10
10 CFU/kg once daily for 10 days in mice treated with chronic unpredictable stress (CUS) treated or vehicle. Depression-like behaviors were assessed using the sucrose preference test (SPT), the forced swimming test (FST), and the tail suspension test (TST). The mRNA and/or protein expression of interleukin-1β (IL-1β), IL-6, tumor necrosis factor-α (TNF-α), IL-4, IL-10, and chitinase-3-like protein 3 (CHI3L1, also known as Ym-1), as well as the concentration of nitrite, malondialdehyde (MDA), glutathione (GSH), and brainderived neurotrophic factor (BDNF) in the hippocampus and medial prefrontal cortex were examined. Results: The BLLL formula treatment at a dose of 8 x 1010 CFU/kg, but not at a dose of 2 or 4 x 1010 CFU/kg, improved CUS-induced depression-like behaviors in mice, as shown by the decrease in immobility time in the TST and FST and the increase in sucrose intake in the SPT. Further analysis revealed that BLLL treatment suppressed the CUS-induced increase in IL-1β, IL-6, and TNF-α mRNA and protein levels, as well as the CUS-induced decrease in IL-4, IL-10, and Ym-1 mRNA and/or protein levels in the hippocampus and medial prefrontal cortex. In addition, treatment with the BLLL formula countered the CUS-induced increase in nitrite and MDA levels and the CUS-induced decrease in GSH content and BDNF concentration in the hippocampus and medial prefrontal cortex. Conclusion: These results demonstrate that the novel probiotic formula BLLL ameliorates chronic stress-induced depression-like behavior in mice by suppressing neuroinflammation and oxido-nitrosative stress in the brain.

Probiotics are becoming increasingly popular as eco-friendly alternatives in aquaculture. However, there is limited research on their impacts on the reproductive efficiency of Red Tilapia (Oreochromis niloticus x O. mossambicus) broodstock. Therefore, this experiment aimed to explore the combined effects of selective probiotics Bacillus subtilis and B. licheniformis (BSL; 1:1) added to water on blood hematology, serum metabolites, gonadal histology, reproductive performance, and reproductive associated genes in Red Tilapia broodstock. Tilapia broodfish weighing 140–160 g were stocked in four treatment groups: control (T0), and the other three groups were added different levels of BSL to the water as follows: T1 (0.01 g/m3), T2 (0.02 g/m3), and T3 (0.03 g/m3), respectively. Results indicate that BSL administration significantly improved RBCs, hemoglobin, hematocrit, MCH, and MCHC, with the highest improvement seen in the T3 group (P < 0.05). BSL added to the fish water significantly enhanced serum protein fractions (total protein, albumin, and globulins), while AST, ALT, ALP, creatinine, uric acid, and glucose were significantly diminished in a dose-dependent way (P < 0.05). Adding 0.02–0.03 g/ m3 of BSL resulted in higher antioxidant status (superoxide dismutase and catalase) compared to other groups (P < 0.05). Testosterone levels were higher in T3 than in other groups (P < 0.05). All female hormones (LH, FSH, estradiol, and progesterone) were substantially augmented by the addition of BSL. Additionally, the BSL groups exhibited higher GSI, HSI, VSI (male only), egg diameter (mm), mean number of fry/fish, and mean fry weight (g) compared to the control group (P < 0.05). Expression of reproductive-associated genes (vasa, nanos1a, nanos2, dnd1, pum1, AMH, and vtg) were significantly up-regulated in the gonads of fish in the 0.03 g/m3 treatment. The histological gonadal structure exhibited that BSL improved gonad maturation in both genders of Tilapia fish. Overall, adding a mixture of B. subtilis and B. licheniformis (0.03 g/m3 water) can accelerate reproductive performance in Red Tilapia through up-regulation of reproductive genes and enhance the health profile.

Background Methods Results Conclusion Few studies have examined long‐term outcomes following oral immunotherapy (OIT); none have examined long‐term risks and benefits associated with distinct clinical outcomes (desensitization, remission).Participants completing the probiotic and peanut oral immunotherapy (PPOIT) ‐003 randomized trial were enrolled in a follow‐on study, PPOIT‐003LT. Peanut ingestion, reactions, and health‐related quality of life (HRQOL) were monitored prospectively. Outcomes at 1‐year and 2‐years post‐treatment were examined by treatment group and by post‐OIT clinical outcome (remission, desensitization without remission [DWR], allergic).86% (151/176) of eligible children enrolled. Post‐treatment peanut ingestion at 2‐years post‐treatment were similar for PPOIT (86.7%) and OIT (78.7%) groups, both higher than placebo (10.3%). Reactions reduced over time for all treatment and clinical outcome groups (PPOIT 31.7% to 23.3%, OIT 37.7% to 19.7%, placebo 13.8% to 6.9%; remission 27.5% to 15.9%; DWR 57.9% to 36.8%; allergic 11.6% to 7%). At 2‐years post‐treatment, similar proportions of remission and allergic participants reported reactions (RD 0.09 (95%CI −0.03, 0.20), p = .127), whereas more DWR participants reported reactions than remission (remission vs DWR: RD −0.21 (95%CI −0.39; −0.03), p = .02) and allergic (DWR vs allergic: RD 0.30 (95%CI 0.13, 0.47), p = .001) participants. At 2‐years post‐treatment, 0% remission versus 5.3% DWR versus 2.3% allergic participants reported adrenaline injector usage. Remission participants had significantly greater HRQOL improvement (adjusted for baseline) compared with both DWR (MD −0.54 (95%CI −0.99, −0.10), p = .017) and allergic (MD −0.82 (95%CI −1.25, −0.38), p < .001).By 2‐years post‐treatment, remission participants reported fewer reactions, less severe reactions and greater HRQOL improvement compared with DWR and allergic participants, indicating that remission is the patient‐preferred treatment outcome over desensitization or remaining allergic.

Background: In this study, a probiotic mixture (Honeybeeotic) consisting of seven bacterial strains isolated from a unique population of honeybees (Apis mellifera ligustica) was used. That honeybee population was located in the Roti Abbey locality of the Marche Region in Italy, an area isolated from human activities, and genetic contamination from other honeybee populations. The aim was to investigate the effects of this probiotic mixture on the innate immunity and intestinal microbiome of healthy common honeybees in two hives of the same apiary. Hive A received a diet of 50% glucose syrup, while hive B received the same syrup supplemented with the probiotics, both administered daily for 1 month. To determine whether the probiotic altered the immune response, phenoloxidase activity and hemolymph cellular subtype count were investigated. Additionally, metagenomic approaches were used to analyze the effects on gut microbiota composition and function, considering the critical role the gut microbiota plays in modulating host physiology. Results: The results revealed differences in hemocyte populations between the two hives, as hive A exhibited higher counts of oenocytoids and granulocytes. These findings indicated that the dietary supplementation with the probiotic mixture was safe and well-tolerated. Furthermore, phenoloxidase activity significantly decreased in hive B (1.75 ± 0.19 U/mg) compared to hive A (3.62 ± 0.44 U/mg, p < 0.005), suggesting an improved state of well-being in the honeybees, as they did not require activation of immune defense mechanisms. Regarding the microbiome composition, the probiotic modulated the gut microbiota in hive B compared to the control, retaining core microbiota components while causing both positive and negative variations. Notably, several genes, particularly KEGG genes involved in amino acid metabolism, carbohydrate metabolism, and branched-chain amino acid (BCAA) transport, were more abundant in the probiotic-fed group, suggesting an effective nutritional supplement for the host. Conclusions: This study advocated that feeding with this probiotic mixture induces beneficial immunological effects and promoted a balanced gut microbiota with enhanced metabolic activities related to digestion. The use of highly selected probiotics was shown to contribute to the overall well-being of the honeybees, improving their immune response and gut health. [ABSTRACT FROM AUTHOR]

Garcinia kola Heckel seed is widely used in the African traditional medicine as a aphrodisiac and male fertility enhancer. Probiotics can reestablish glucose homeostasis and improve blood lipid profiles by altering the composition of the intestinal flora. The study was planned to assess the efficacy of co-administration of Garcinia kola seed aqueous infusion and probiotic yoghurt in the management of diabetes and associated male fertility-stimulating hormones abnormalities. G. kola seed infusion was prepared, assessed for radical scavenging capacity, total phenolic content and phenolic profile using HPLC. Fermented yoghurt was prepared and inoculated with probiotic mixture. Rats were given a high-fat diet for four weeks and received an intraperitoneal injection of streptozotocin (30 mg/kg) to induce type 2 diabetes. Diabetic rats were received 200 mg/kg freeze-dried infusion of G. kola seed, probiotics yoghurt, and probiotic yoghurt mixed with G. kola once a day for four weeks. The levels of glucose, insulin, testosterone, follicle-stimulating hormone, luteinizing hormone, inflammatory indicators, oxidative markers, lipid profiles and liver as well as kidney biochemical indicators were measured. The administration of G. kola seed, probiotic yoghurt, or their combination to diabetic rats demonstrated potential anti-diabetic effects as evidenced by the down-regulation in glucose, insulin, lipid profile, oxidative markers, and inflammatory markers simultaneously with an up-regulation in testosterone, FSH, and LH levels compared to diabetic rats. G. kola seed, probiotic yoghurt, or their combination increased testosterone, FSH, and LH levels and are thought to have therapeutic promise for T2DM and its related oxidative stress.

Background and Aim: The existing data demonstrate that gut microbiota is involved in regulating mineral metabolism in cattle, although the data are quite contradictory. The study aimed to evaluate Saccharomyces cerevisiae-based probiotic's effects on gut microbiota, systemic metabolism, and dairy cows' essential trace element and mineral body burden. Materials and Methods: Fifteen cows received a daily supplement of a 50 g S. cerevisiae-based probiotic, fortified with methionine, choline, eugenol, cinnamaldehyde, and Capsicum oleoresin, for a month. 16S metagenomic sequencing was used to evaluate the taxonomic features of fecal microbiota. Serum trace elements and minerals levels were determined through inductively coupled plasma mass spectrometry. Results: Supplementation with S. cerevisiae-based probiotic complex significantly increased alpha and beta diversity, as well as the abundance of Mediterranea and Clostridium IV within the Bacillota phylum, whereas that of Bacteroidota and specifically unclassified Bacteroidales and unclassified Oscillospiraceae decreased. Following probiotic supplementation with the S. cerevisiae-based complex, gut microbiota modulation led to a significant boost in circulating levels of calcium, copper, selenium, and zinc. Creatinine levels decreased while total cholesterol levels increased within normal limits in the serum analysis. Conclusion: The observed improvement in trace elements and minerals in dairy cows might be due to changes in intestinal microflora caused by supplementation. Therefore, probiotic supplementation in cattle may be considered a potential tool for improvement of mineral nutrition in cattle. However, the influence of probiotic treatment and modulation of mineral metabolism on milk productivity and overall performance in cattle is yet to be estimated. [ABSTRACT FROM AUTHOR]

Eight-week feeding trial was conducted to estimate the effects of dietary probiotic (P), garlic (G), and onion (O) powders on growth, hematology, and serum parameters in the juvenile rainbow trout (Oncorhynchus mykiss). Seven practical diets were formulated to be isonitrogenous (49% protein) and isolipidic (20% lipid) and the diets included the P, O, and G at the concentrations of 0.1, 1, and 1%, respectively, at the replace of wheat flour. Rainbow trout fed the G supplemented diet displayed a higher specific growth rate (SGR) when compared with fish fed the P and the mix of probiotics and onion (PO) (P < 0.05). The feed conversion ratio (FCR) of the fish fed the G diet was lower than the P diet (P < 0.05). Net protein utilization (NPU) of the juveniles fed the O and PO diets was higher than the other experimental groups, except the G (P < 0.05). The group fed the G diet exhibited significant differences in the packed cell volume (PCV) and hemoglobin (Hb) levels of groups fed the P and PO (P < 0.05). There were no significant differences in terms of white blood cell (WBC) and red blood cell (RBC) counts (P > 0.05). Significant differences were recorded among the serum alkaline phosphatase (ALP), while juveniles fed the G and PG diets were higher than the P and O groups (P < 0.05). The results of this study demonstrated that supplementing diets with garlic can improve some growth parameters such as SGR and PER for rainbow trout. [ABSTRACT FROM AUTHOR]

Freeze drying has been well applied in the preparation of high-efficiency viability probiotic powders. However, the process is generally accompanied by probiotic viability deficiency, which poses a problem for further application. In this study, various kinds of cryoprotectant formulations (skim milk, maltodextrin, and sucrose) were tested to enhance the survival of Lactiplantibacillus plantarum NBC99 after freezing and freeze-drying. An I-optimal experimental design-oriented optimization model was presented to optimize the cryoprotective medium, and the highest cell survival was observed with 25% skim milk, 8.71% maltodextrin, and 1.13% sucrose cryoprotectant as the optimum condition. L. plantarum NBC99 has been a good potential strain for the manufacture of an industrial probiotic, and this research has aimed to investigate the long-term protective effects of optimum cryoprotectant formulations on the viability of bacteria. The results showed the potential value of freeze-dried probiotic L. plantarum NBC99 culture for commercialization. [ABSTRACT FROM AUTHOR]

Simple Summary: In the present meta-analysis of randomized controlled trials, probiotic fermented milk supplementation appeared to be beneficial in lowering the levels of fasting plasma glucose, HbA1c, total cholesterol, and C-reactive protein. While these findings are encouraging, they should be interpreted cautiously, as considerable limitations of the included trials and analyses precluded solid conclusions. Modulating gut microbiota composition through probiotic administration has been proposed as a novel therapy for type 2 diabetes mellitus (T2DM), and fermented milk is arguably the most common and ideal probiotic carrier. The present meta-analysis was performed to assess the effects of probiotic fermented milk supplementation on glucose and lipid metabolism parameters and inflammatory markers in patients with T2DM using published data from randomized controlled trials (RCTs). The PubMed, Web of Science, and Cochrane Library databases were searched for relevant RCTs. A random-effects model was used to generate the weighted mean difference (WMD) and 95% confidence interval (95% CI). Probiotic fermented milk supplementation reduced the levels of fasting plasma glucose (MD = −17.01, 95% CI −26.43, −7.58 mg/dL; n = 7), hemoglobin A1c (MD = −0.47, 95% CI −0.74, −0.21%; n = 7), total cholesterol (MD = −5.15, 95% CI −9.52, −0.78 mg/dL; n = 7), and C-reactive protein (MD = −0.25, 95% CI −0.43, −0.08; n = 3) but did not significantly affect the levels of HOMA-IR (MD = −0.89, 95% CI −2.55, 0.78; n = 3), triglyceride (MD = −4.69, 95% CI −14.67, 5.30 mg/dL; n = 6), low-density lipoprotein cholesterol (MD = −4.25, 95% CI −8.63, 0.13 mg/dL; n = 7), high-density lipoprotein cholesterol (MD = 1.20, 95% CI −0.96, 3.36 mg/dL; n = 7), and tumor necrosis factor-alpha (MD: −0.58, 95% CI −1.47, 0.32 pg/mL; n = 2). In summary, the present findings provide a crude indication of the potential benefits of probiotic fermented milk supplementation in improving glucose and lipid metabolism and inflammation in patients with T2DM. However, more robust evidence is needed to determine the clinical significance of probiotic fermented milk in the management of T2DM. [ABSTRACT FROM AUTHOR]

Simple Summary: China's deer population is rich in resources and species; how to improve the health status of the deer population and reduce the occurrence of intestinal diseases is a necessary direction for current research. In this study, Enterococcus faecalis was used as the research object to explore the effect of lactic acid bacteria on deer growth performance and intestinal health and to further investigate the role played by lactic acid bacteria on the intestinal health status of deer. The results of this study showed that the addition of Enterococcus faecalis to the feed promoted weight gain, improved immune function, altered the structure of the intestinal flora of fallow deer, especially increasing the abundance of Firmicutes phylum, and increased the abundance of the Ruminococcaceae and Lacertococcaceae at the same phylum as that of Enterococcus faecalis. Furthermore, metabolomic analyses also revealed that Enterococcus faecalis supplementation increased the metabolism of lipids, carbohydrates and phospholipids by the intestinal microbiota. In conclusion, this study revealed the beneficial effects of lactic acid bacteria on growth traits, immunity and intestinal health of deer and provided a scientific basis for the further development of deer-specific probiotic products to promote intestinal health and reduce intestinal diseases in deer species in the future. Intestinal diseases are one of the diseases that affect the growth and immunity of deer. Currently, more lactic acid bacteria (LAB) are available as feed additives to improve the intestinal ecological balance of ruminants in production practices. In this study, Enterococcus faecalis was supplemented in the feed of fallow deer for 170 d, and body weights, blood indices and immune levels of fallow deer were counted at 35, 65 and 170 d. The effects of Enterococcus faecalis on the intestinal microbiota and the metabolism of fallow deer were analysed using 16S rDNA and UPLC-MS/MS methods. The results showed that the addition of Enterococcus faecalis to the diet improved body weight and immune function and increased the aggregation of gut microbiota in fallow deer. The addition of Enterococcus faecalis altered the community structure of intestinal microorganisms in fallow deer and increased the number of beneficial bacteria. In addition, combined with metabolomics analysis, it was found that supplementation with Enterococcus faecalis significantly altered the metabolites of fallow deer, mainly regulating lipid metabolism, carbohydrate metabolism and phospholipid metabolism. In conclusion, this study presents, for the first time, evidence that the LAB strain Enterococcus faecalis can be used as a potential probiotic for deer and points to a new direction for the treatment of intestinal disorders in the deer family.

The list of standard abbreviations for JDS is available at adsa.org/jds-abbreviations-24. Nonstandard abbreviations are available in the Notes. Objectives were to evaluate the effects of a multistrain Bacillus -based (Bacillus subtilis and Bacillus pumilus blend) direct-fed microbial (DFM) on production, metabolism, inflammation biomarkers and gastrointestinal tract (GIT) permeability during and following feed restriction (FR) in mid-lactation Holstein cows. Multiparous cows (n = 36; 138 ± 53 DIM) were randomly assigned to 1 of 3 dietary treatments: (1) control (CON; 7.5 g/d rice hulls; n = 12), (2) DFM10 (10 g/d Bacillus DFM, 4.9 × 109 cfu/d; n = 12) or 3) DFM15 (15 g/d Bacillus DFM, 7.4 × 109 cfu/d; n = 12). Before study initiation, cows were fed their respective treatments for 32 d. Cows continued to receive treatments during the trial, which consisted of 3 experimental periods (P): P1 (5 d) served as baseline for P2 (5 d), during which all cows were restricted to 40% of P1 DMI, and P3 (5 d), a "recovery" where cows were fed ad libitum. On d 4 of P1 and on d 2 and 5 of P2, GIT permeability was evaluated in vivo using the oral paracellular marker Cr-EDTA. As anticipated, FR decreased milk production, insulin, glucagon, and BUN but increased nonesterified fatty acids. During recovery, DMI rapidly increased on d 1 then subsequently decreased (4.9 kg) on d 2 before returning to baseline, whereas milk yield slowly increased but remained decreased (13%) relative to P1. The DFM10 cows had increased DMI and milk yield relative to DFM15 during P3 (10%). Overall, milk lactose content was increased in DFM cows relative to CON (0.10 percentage units), and DFM10 cows tended to have increased lactose yield relative to CON and DFM15 during P3 (8% and 10%, respectively). No overall treatment differences were observed for other milk composition variables. Circulating glucose was quadratically increased in DFM10 cows compared with CON and DFM15 during FR and recovery. Plasma Cr area under the curve was increased in all cows on d 2 (9%) and 5 (6%) relative to P1. Circulating LPS binding protein (LBP), serum amyloid A (SAA), and haptoglobin (Hp) increased in all cows during P2 compared with baseline (31%, 100%, and 9.0-fold, respectively). Circulating Hp concentrations continued to increase during P3 (274%). Overall, circulating LBP and Hp tended to be increased in DFM15 cows relative to DFM10 (29% and 81%, respectively), but no treatment differences were observed for SAA. Following feed reintroduction during P3, fecal pH initially decreased (0.62 units), but returned to baseline levels whereas fecal starch markedly increased (2.5-fold) and remained increased (82%). Absolute quantities of a fecal Butyryl-CoA CoA transferase (but) gene associated with butyrate synthesis, collected by fecal swab were increased in DFM10 cows compared with CON and DFM15 cows. In summary, FR increased GIT permeability, caused inflammation, and decreased production. Feeding DFM10 increased some key production and metabolism variables and upregulated a molecular biomarker of microbial hindgut butyrate synthesis, while DFM15 appeared to augment immune activation.

Camel milk yoghurts were created using probiotic lactic acid bacteria (LAB) with exopolysaccharide (EPS) production capabilities. Lacticaseibacilluscasei ATCC 393, identified as the most efficient EPS producer, was incorporated into conventional yoghurt culture. We compared the effects of adding L. casei ATCC 393 with EPS powder (SLLP) against lactulose. Evaluations included LAB, yeast, mould, cytotoxicity and IC50 values in the samples. The results demonstrated increased bacterial counts, LAB viability, viscosity, antiproliferative effects and a lower IC50 in SLLP, indicating the potential application of EPS‐producing L. casei ATCC 393 and its derived EPS in the development of functional foods.

Inflammatory bowel disease (IBD) imposes a significant impact on the quality of life for affected individuals. However, there was a current lack of a systematic summary regarding the latest epidemic trends and the underlying pathogenesis of IBD. This highlights the need for a thorough examination of both the epidemiological aspects of IBD and the specific mechanisms by which lactic acid bacteria (LAB) contribute to mitigating this condition. In developed countries, higher incidences and death rates of IBD have been observed, influenced by a combination of environmental and genetic factors. LAB offer significant advantages and substantial potential for enhancing IBD treatment. LAB's capabilities include the production of bioactive metabolites, regulation of gut immunity, protection of intestinal mechanical barriers, inhibition of oxidative damage, and restoration of imbalanced gut microbiota. The review suggests that screening effective LAB using cell models and metabolites, optimizing LAB intake through dose‐effect studies, enhancing utilization through nanoencapsulation and microencapsulation, investigating mechanisms to deepen the understanding of LAB, and refining clinical study designs. These efforts aim to contribute to comprehending the epidemic trend, pathogenesis, and treatment of IBD, ultimately fostering the development of targeted therapeutic products, such as LAB‐based interventions.

Obesity in adolescence is increasing in frequency and is associated with elevated proinflammatory cytokines and chronic pain in a sex-dependent manner. Dietary probiotics may mitigate these detrimental effects of obesity. Using a Long-Evans adolescent and adult rat model of overweight (high-fat diet (HFD) – 45% kcal from fat from weaning), we determined the effect of a single-strain dietary probiotic [Lactiplantibacillus plantarum 299v (Lp299v) from weaning] on the theoretically increased neuropathic injury-induced pain phenotype and inflammatory cytokines. We found that although HFD increased fat mass, it did not markedly affect pain phenotype, particularly in adolescence, but there were subtle differences in pain in adult male versus female rats. The combination of HFD and Lp299v augmented the increase in leptin in adolescent females. There were many noninteracting main effects of age, diet, and probiotic on an array of cytokines and adipokines with adults being higher than adolescents, HFD higher than the control diet, and a decrease with probiotic compared with placebo. Of particular interest were the probiotic-induced increases in IL12p70 in female adolescents on an HFD. We conclude that a more striking pain phenotype could require a higher and longer duration caloric diet or a different etiology of pain. A major strength of our study was that a single-strain probiotic had a wide range of inhibiting effects on most proinflammatory cytokines. The positive effect of the probiotic on leptin in female adolescent rats is intriguing and worthy of exploration. NEW & NOTEWORTHY: A single-strain probiotic (Lp299v) had a wide range of inhibiting effects on most proinflammatory cytokines (especially IL12p70) measured in this high-fat diet rat model of mild obesity. The positive effect of probiotic on leptin in female adolescent rats is intriguing and worthy of exploration. [ABSTRACT FROM AUTHOR]

Cadmium (Cd) causes significant oxidative stress, which can lead to major clinical complications and tissue destruction. In this study, the antioxidant and anti-inflammatory effects of a mixture of Iranian probiotic strains were evaluated in Cd-exposed rats. Twenty-one adult male Wistar rats were randomized into three groups of seven rats: the control group, Cd-treated (3 mg/kg, a single dose) animals, and the rats treated with Cd + probiotic (Cd + Pro) for 30 days. Histological changes were assessed using hematoxylin and eosin staining, as well as Masson's trachoma staining. The qRT-PCR method was used for evaluating pro-inflammatory genes' expression. Liver biomarkers (ALT, ALP, and AST), biochemical enzymes, and blood parameters were measured using commercial kits, and hematological parameters were determined in both Cd- and the Cd + Pro–treated groups. Histopathologically, results revealed that the native probiotic mixture improved the function of Cd-treated liver cells, compared with Cd-treated rats. Also, positive changes of blood parameters and liver biomarker were observed in the treated group compared with the Cd-treated group. There was a down-regulation of TNF-α and IL-6 genes' expression in Cd + Pro–treated compared with the Cd-treated group. In addition, Cd + Pro–treated rats displayed lower production of lipid peroxides, lower levels of hepatic toxicity biomarkers, and increased levels of CAT and SOD antioxidant biomarkers compared to Cd-treated animals. Iranian native probiotics showed antioxidant and anti-inflammatory properties, and it is suggested to investigate their health benefits in animal studies in the future. [ABSTRACT FROM AUTHOR]

The application of probiotics in functional foods has gained significant interest due to their various beneficial effects to human when consumed in adequate amounts. However, the low survivability of probiotics subjected to adverse environmental conditions during processing, storage and gastrointestinal passage limited their commercial applications. Double emulsion microbial encapsulation is a promising approach to provide probiotic living cells with a full protection to resist adverse environmental conditions. Based on numerous cases of double emulsions applied for probiotic encapsulation, this report reviews various factors influencing the encapsulation yield and viability of probiotics, including emulsification methods, emulsifier selection, effect of probiotics, and modification of emulsification technique, also the targeted release mechanisms of these double emulsions triggered by various manners. This information can be useful to optimize the formulation and emulsification technique of double emulsion in order to improve the use efficacy and beneficial effects of probiotics in different commercial products.

- Abstract
Levan is a type of fructan with β-(2, 6) fructosyl linkage. In recent years, levan has been used in the medicinal, food and chemical industries for its excellent physicochemical properties of good thermal stability, low viscosity, pseudoplasticity, and non-swelling in water. The levansucrase is key enzyme responsible for biosynthesis of levan from substrate sucrose. In the present study cell lysate of Escherichia coli was used as support for convenient immobilization of Ba-SacB (i.e., Ba-SacB-Cell-Lysate) under the action of dopamine. Compared with the free Ba-SacB, the Ba-SacB-Cell-Lysate showed surprisingly enhanced pH stability in the pH range 6–9, and improved relative activities in the pH ranges 4–5 and 7–10. With the presence of 10% (v/v) butyl alcohol, 5mmol/L Fe3+, and after vortex for 90 min, the Ba-SacB-Cell-Lysate showed up to 14.32 times, 4.63 times, and 9.2 times higher relative activities than the free Ba-SacB. The Ba-SacB-Cell-Lysate kept nearly 81% of the residual activity after 9 cycles of reuse. The fructo-oligosaccharide syrup (FOS) was efficiently produced through the catalysis of levanase with the substrate of levan produced by Ba-SacB-Cell-Lysate, and the preparation conditions were optimized by Box-Behnken response surface methodology.
