Abstract

Background: Pineapple plant (Ananas comosus) is one of the largest productions in Asia and its increasing production has generated a huge amount of pineapple wastes. Pineapple plant stem is made up of high concentration of starch which can potentially be converted into value-added products, including amino acids. Due to the increasing demand in animal feed grade amino acids, especially for methionine and lysine, the utilisation of cheap and renewable source is deemed to be an essential approach. This study aimed to produce amino acids from pineapple plant stem hydrolysates through microbial fermentation by Pediococcus acidilactici Kp10. Dextrozyme was used for hydrolysis of starch and Celluclast 1.5 L for saccharification of cellulosic materials in pineapple plant stem. Results: The hydrolysates obtained were used in the fermentation to produce methionine and lysine. Pineapple plant stem showed high starch content of 77.78%. Lignocellulosic composition of pineapple plant stem consisted of 46.15% hemicellulose, 31.86% cellulose, and 18.60% lignin. Saccharification of alkaline-treated pineapple plant stem gave lower reducing sugars of 13.28 g/L as compared to untreated, where 18.56 g/L reducing sugars obtained. Therefore, the untreated pineapple plant stem was selected for further process. Starch hydrolysis produced 57.57 g/L reducing sugar (100% hydrolysis yield) and saccharification of cellulosic materials produced 24.67 g/L reducing sugars (56.93% hydrolysis yield). The starch-based and cellulosic-based of pineapple plant stem were subjected as carbon source in methionine and lysine production by P. acidilactici Kp10. Conclusions: In conclusion, higher methionine and lysine production were produced from starch-based hydrolysis (40.25 mg/L and 0.97 g/L, respectively) as compared to cellulosic-based saccharification (37.31 mg/L and 0.84 g/L, respectively) of pineapple plant stem.

2. New Experimental Autoimmune Hepatitis Data Have Been Reported by Investigators at Huazhong University of Science and Technology (L-lysine Supplementation Attenuates Experimental Autoimmune Hepatitis In a Chronic Murine Model).

Abstract

A recent study conducted at Huazhong University of Science and Technology in Hubei, China, explored the potential protective effect of L-lysine supplementation against autoimmune hepatitis (AIH) and its underlying mechanisms. The study used a chronic murine model of AIH and found that L-lysine supplementation partially reversed liver injury, decreased proinflammatory cytokine expression, reduced T lymphocyte infiltration, and alleviated liver fibrosis. The researchers concluded that L-lysine supplementation may serve as a novel nutrition support approach for AIH. This research has been peer-reviewed and published in Experimental Animals.

Abstract

A recent study conducted by researchers at Tianjin University of Science and Technology in China has found that epsilon-poly-L-lysine (e-PL), a natural antimicrobial peptide, has the potential to manage bacterial brown blotch disease in postharvest edible mushrooms. The study demonstrated that concentrations of e-PL at or above 150 mg L-1 effectively inhibited the growth of Pseudomonas tolaasii, the bacteria responsible for brown blotch disease, in Agaricus bisporus mushrooms. The researchers identified several mechanisms by which e-PL acts against P. tolaasii, including damaging the cell morphology and membrane integrity, interacting with intracellular proteins and DNA, and inhibiting the activation of certain enzymes. These findings suggest that e-PL could be a promising tool for controlling bacterial brown blotch disease in edible mushrooms. [Extracted from the article]

Abstract

And an 8.62 times increase of solubility was observed after pH 12.5 + 80 treatment compared to the control SPPI sample which was extracted at pH 9.0 without pH shift treatment. In this study, combined treatments of pH shift and heating were performed to improve the solubility of SPPI and to reduce the content of LAL."

Abstract

A trial was conducted to evaluate the requirement of digestible lysine at various protein levels in the diet of WLH layers (BV-300) from 25-44 weeks of age. Layers (528) were fed with diets containing two protein levels i.e. 13.36 and 15.78% each with 5% concentration variations of lysine (0.50, 0.55, 0.60, 0.65, and 0.70) and a control with 17% CP and 0.70% lysine. Each diet was fed to six replicates of eight birds. Egg production, feed intake, body weight were not influenced either by the concentration of lysine or by level of protein in diet. Increased (P d" 0.05) egg weight and egg mass were observed with increasing lysine in diets. Better feed efficiency was observed with increasing lysine concentration. It can be concluded that WLH layers require approximately 0.65% lysine with 13.36% CP or 0.63% lysine with 15.78% CP (i.e. 598.80 vs 570 mg/h/day) in diet. [ABSTRACT FROM AUTHOR]

Abstract

The feasibility of making fish sauce with added lysine was studied. A difference was found in quality of the volatile compounds detected from the control and from the lysine-added samples. High concentration of lysine did not significantly affect acceptance due to aroma but reduced acceptance of flavor and color. Addition of lysine could feasibly increase protein level of fish sauce. Sensory evaluation in terms of overall quality showed that addition of up to 2.0% lysine was quite acceptable. [ABSTRACT FROM AUTHOR]

Abstract

Highly pathogenic avian H5N1 influenza A viruses have spread throughout Asia since 2003. These viruses are highly lethal to birds and humans. Of the 74 confirmed human cases, 49 were fatal (as of Mar 30, 2005), raising concerns of a possible pandemic by these viruses. Despite the well-established pathogenicity of these viruses, the molecular mechanism for expressing such high virulence remains elusive. Thus, we examined the pathogenicity of the H5N1 viruses isolated in Vietnam in 2003-2004 using animal models (mouse, duck, and ferret). Viruses from humans were generally more pathogenic in mice and ferrets than those from birds. Indeed, one human isolate was even lethal to ferrets. The human isolate possessing Lys at amino acid position 627 of PB2 was more virulent than that possessing Glu at this position, underscoring the importance of Lys at this position 627 of PB2 for efficient growth in mammals.
