fuller, in 1989, described probiotic microorganisms as “a live microbial feed supplement,which beneficially affects the host animal, by improving its intestinal microbial balance”.saccharomyces cerevisiae var. boulardii (s.boulardii) is an accurate probiotic yeast idol.the detection and budding of s.boulardiiis firmly related to the impression of healthinessto promote microorganisms from foodst...

endophytes are important resources of bioactive compounds and due to their potential in theproduction of secondary metabolites, they are regarded as a potential reservoir ofbiotechnological applications. in this study, the bioactivity of bacteria and yeasts endophytesresiding in thymus sp. was evaluated. during april to october 2011, symptomless and healthytissues of thymus sp. were collected. ...

Kombucha is a traditional fermentation of sweetened tea, involving a symbiosis of yeast species and acetic acid bacteria. Despite reports of different yeast species being associated with the fermentation, little is known of the quantitative ecology of yeasts in Kombucha. Using oxytetracycline-supplemented malt extract agar, yeasts were isolated from four commercially available Kombucha products...

The mechanisms regulating the coordinate activation of tens of thousands of replication origins in multicellular organisms remain poorly explored. Recent advances in genomics have provided valuable information about the sites at which DNA replication is initiated and the selection mechanisms of specific sites in both yeast and vertebrates. Studies in yeast have advanced to the point that it is ...

The diversity and the composition of the yeast micropopulation significantly contribute to the sensory characteristics of wine. The growth of each wine yeast species is characterized by a specific metabolic activity, which determines concentrations of flavour compounds in the final wine. However, it must be underlined that, within each species, significant strain variability has been recorded. ...

Traditional nata de coco fermentation often results in inconsistent thickness. From the producer's perspective, thin sheets are detrimental because most media will be wasted. The main cause of this condition may that microbial population starter culture is different each batch. It necessary to observe cultured community on various qualities available thick and design a better culture. This stud...

background: glutathione (gsh) is a non-protein thiol compound, which plays an important role in the response to oxidative stress and nutritional stress. the aim of this study was to isolate indigenous s. cerevisiae strains capable of effectively produce gsh. methods: one hundred-twenty sweet fruit samples were collected. the strains were isolated on yeast glucose chloramphenicol (ygc) agar medi...
