Abstract

The intensified attention to health, the growth of an elderly population, the changing lifestyles, and the medical discoveries have increased demand for natural and nutrient‐rich foods, shaping the popularity of microalgae products. Microalgae thanks to their metabolic versatility represent a promising solution for a 'green' economy, exploiting non‐arable land, non‐potable water, capturing carbon dioxide (CO2) and solar energy. The interest in microalgae is justified by their high content of bioactive molecules, such as amino acids, peptides, proteins, carbohydrates, polysaccharides, polyunsaturated fatty acids (as ω‐3 fatty acids), pigments (as β‐carotene, astaxanthin, fucoxanthin, phycocyanin, zeaxanthin and lutein), or mineral elements. Such molecules are of interest for human and animal nutrition, cosmetic and biofuel production, for which microalgae are potential renewable sources. Microalgae, also, represent effective biological systems for treating a variety of wastewaters and can be used as a CO2 mitigation approach, helping to combat greenhouse gases and global warming emergencies. Recently a growing interest has focused on extremophilic microalgae species, which are easier to cultivate axenically and represent good candidates for open pond cultivation. In some cases, the cultivation and/or harvesting systems are still immature, but novel techniques appear as promising solutions to overcome such barriers. This review provides an overview on the actual microalgae cultivation systems and the current state of their biotechnological applications to obtain high value compounds or ingredients. Moreover, potential and future research opportunities for environment, human and animal benefits are pointed out. © 2023 The Authors.

Abstract

There has been a growing demand towards alternative protein sources due to population growth and increasing consumer awareness on sustainability and environmental issues. Proteins from various plant, marine, insect and microbial sources are considered as excellent alternatives to substitute traditional animal-based proteins due their relatively low cost, sustainable production and nutritional value. This work is an overview of the physicochemical properties, functionality and nutritional quality of novel protein sources. Current information on the proximate composition, amino acid profile, digestibility, physicochemical and functional properties is presented. Effects of extraction method applied for obtaining protein ingredients from novel sources on protein composition, functionality and nutritional quality are discussed. Findings of some of the recent studies focusing on modification of protein structure and improvement of functionality are reviewed. Potential end product applications and challenges related to the production and use of protein ingredients obtained from novel sources are discussed. Furthermore, future research recommendations are presented. [ABSTRACT FROM AUTHOR]

Abstract

Bifidobacteria have long been recognized as bacteria with probiotic and therapeutic features. The aim of this work is to characterize the Bifidobacterium asteroides BA15 and BA17 strains, isolated from honeybee gut. An in-depth assessment was carried out on safety properties (antibiotic resistance profiling, β-haemolytic, DNAse and gelatinase activities and virulence factor presence) and other properties (antimicrobial activity, auto-aggregation, co-aggregation and hydrophobicity). Based on phenotypic and genotypic characterization, both strains satisfied all the safety requirements. More specifically, genome analysis showed the absence of genes encoding for glycopeptide (vanA, vanB, vanC-1, vanC-2, vanD, vanE, vanG), resistance to tetracycline (tet-M, tet-L and tetO), and virulence genes (asa1, gelE, cylA, esp, hyl).

Abstract

La valorizzazione dei sottoprodotti agroalimentari richiede la rispondenza a criteri di economicità ed innovazione che possono includere la progettazione di nuovi prodotti a medio e ad elevato valore aggiunto. In particolare, i sottoprodotti oleari rappresentano una fonte di molecole bioattive, la cui azione benefica è stata riconosciuta dall’EFSA. Recentemente, crescente interesse è rivolto al pâté, sottoprodotto ottenuto dall’estrazione olearia attraverso l’utilizzo del decanter multifase (DMF). Il pâté, caratterizzato da un’elevata umidità, dall’assenza di parti legnose e dalla presenza di composti bioattivi, rappresenta una matrice ideale per la formulazione di nuovi alimenti funzionali. Il presente studio ha avuto lo scopo di valorizzare e stabilizzare il pâté attraverso l’impiego di pool microbici. Fermentazioni guidate sono state allestite ed è stato determinato l’effetto di differenti inoculi microbici sulla cinetica di deamarizzazione. Ceppi appartenenti alle specie Candida boidinii, Wickerhamomyces anomalus e Lactiplantibacillus plantarum sono stati inoculati nel pâté ad una densità finale pari a 107 e 108 UFC/g per i lieviti e per L. plantarum, rispettivamente. Sono state disposte diverse tesi: tre inoculate con le singole culture, due inoculate con i ceppi combinati e una inoculata con la miscela dei tre ceppi. La fermentazione è stata monitorata a differenti tempi, attraverso analisi chimiche e microbiologiche. Inoltre, la cinetica di deamarizzazione della componente fenolica è stata monitorata in HPLC e, a fine fermentazione, la comunità microbica è stata caratterizzata attraverso analisi NGS. La fermentazione si è arrestata dopo 14 giorni, quando il pH ha raggiunto valori di 4.33 e 4.36, nei campioni inoculati con i due lieviti in monocoltura. Le analisi microbiologiche hanno evidenziato una densità cellulare costante dei lieviti, una riduzione della carica mesofila aerobia totale e dei lattobacilli in tutti campioni inoculati. La concentrazione di idrossitirosolo ha presentato una riduzione significativa nei campioni inoculati dopo 2 e 4 giorni, seguita da un incremento dopo 8 e 14 giorni. In particolare, un incremento significativo si è osservato, dopo 8 giorni, nei campioni inculati con C. boidinii in coltura singola, nei campioni inoculati con C. boidinii in associazione con L. plantarum, e nel campione inoculato con W. anomalus in coltura singola, raggiungendo concentrazioni di 275, 261 e 231 mg/L, rispettivamente, confermando una correlazione tra microbiota e processo di deamarizzazione. Le analisi NGS hanno rilevato una diminuzione delle Acetobacteraceae e la dominanza di Saccharomycetes in tutti i campioni. I risultati ottenuti confermano che la valorizzazione microbiologica del pâté può rappresentare una strategia per l'ottenimento di un prodotto funzionale ad alto valore aggiunto. info:eu-repo/semantics/publishedVersion

Abstract

The search for novel brewing strains from non-brewing environments represents an emerging trend to increase genetic and phenotypic diversities in brewing yeast culture collections. Another valuable tool is hybridization, where beneficial traits of individual strains are combined in a single organism. This has been used successfully to create de novo hybrids from parental brewing strains by mimicking natural Saccharomycescerevisiae ale × Saccharomyceseubayanus lager yeast hybrids. Here, we integrated both these approaches to create synthetic hybrids for lager fermentation using parental strains from niches other than beer. Using a phenotype-centered strategy, S. cerevisiae sourdough strains and the S. eubayanus × Saccharomyces uvarum strain NBRC1948 (also referred to as Saccharomyces bayanus) were chosen for their brewing aptitudes. We demonstrated that, in contrast to S. cerevisiae × S. uvarum crosses, hybridization yield was positively affected by time of exposure to starvation, but not by staggered mating. In laboratory-scale fermentation trials at 20 °C, one triple S. cerevisiae × S. eubayanus × S. uvarum hybrid showed a heterotic phenotype compared with the parents. In 2 L wort fermentation trials at 12 °C, this hybrid inherited the ability to consume efficiently maltotriose from NBRC1948 and, like the sourdough S. cerevisiae parent, produced appreciable levels of the positive aroma compounds 3-methylbutyl acetate (banana/pear), ethyl acetate (general fruit aroma) and ethyl hexanoate (green apple, aniseed, and cherry aroma). Based on these evidences, the phenotype-centered approach appears promising for designing de novo lager beer hybrids and may help to diversify aroma profiles in lager beer.

Abstract

The use of Saccharomyces cerevisiaeas starter cultures in winemaking is widespread in all over the world. However, a growing interest in exploring native non-Saccharomycesyeast species as co-starters has emerged, driven by their potential to enhance wine complexity and regional identity. The aim of the present study was to investigate indigenous yeasts from Sicily, to select novel strains with promising technological traits. A comprehensive screening of indigenous S. cerevisiaeand non-Saccharomycesyeasts was conducted across seven locations in Sicily, including the unique volcanic zone of Mount Etna. A total of 95 yeast isolates were obtained and genetically characterized by RFLP-PCR and sequencing of 5.8S-ITS rDNA. Isolates were screened for oenological traits and the most promising, belonging to Starmerella bacillaris, Hanseniaspora uvarum, and Metschnikowia pulcherrimaspecies, were used for single and sequential fermentations in synthetic must. Results revealed a remarkable diversity of physiological traits within and among the species, regarding stress tolerance, enzymatic activity and growth at different temperatures. Notably, isolates of H. uvarumand St. bacillarisexhibited great ethanol tolerance, and the latter also strong glycerol production. Furthermore, M. pulcherrimaexhibited a wide range of aroma-related enzymatic activities, particularly beta-glucosidase. The remarkable diversity, the phenotypic traits of the indigenous yeasts, represents a promise for the improvement of innovative fermentation strategies and for the development of wine indigenous starters related with the region's terroir.

Abstract

The Finnish farmhouse ale sahti is unique in that it is fermented with baking, rather than brewing strains of Saccharomyces cerevisae. The custom of maintaining farmhouse yeast cultures is however no longer practiced in Finland, and much yeast derived diversity in sahti beers has presumably been lost as a consequence. Here, the brewing potential of a number of sourdough derived strains was tested with respect to a number of different fermentation traits. Seven strains originally isolated from Finnish or Italian sourdough cultures were used to ferment high gravity sahti wort (20°P), and fermentation performance together with production of volatile compounds were assessed and compared with a reference baking yeast. Strains differed in terms of fermentation rate, yield, yeast viability and beer flavour profile. All were maltotriose positive, but utilisation varied so that alcohol yield could be greater or lower than that of the reference strain, with values ranging from 6.6 to 7.9% (v/v). Production of aroma compounds was also variable so that it was possible to identify strains producing high levels of esters and those with lower production, which could be used to emphasise flavours originating from raw materials. All strains generated 4‐vinyl guaiacol and so would be suitable for other beers where this is a part of the normal flavour profile. Results suggest that sourdough isolates of S. cerevisiaeare suitable for sahti production, but could also be applied to other beer styles as a way to differentiate products. © 2020 The Authors.
