Characteristics of Different Brewerâs Yeast Strains Used for Non-alcoholic Beverage Fermentation in Media Containing Different Fermentable Sugars
Fermentation characteristics of four strains of brewer's yeast (Saccharomyces cerevisiae strain 70424, S.rouxii strain 2535, S. rouxii strain 2531 and Saccharomyces ludwigii strain 3447) in Yeast Moldbrothcontaining four different fermentable sugars (glucose, fructose, maltose, or sucrose) were studied. Theaim was to consider the suitability of different strain/sugar treatment...
متن کاملSucrose Inversion by Saccharomyces Yeast Cells Immobilized on to Corn Grits
Sucrose hydrolysis was carried Out by Saccharomyces strains. The effective rate of reaction was examined experimentally for 5 different Saccharomyces strains. Two Strains of Schizosaccharomyces and Saccharomyces Carlsbergensis showed the best invertase activity. These two strains showed Michaelien Kinetics in the sucrose concentration up to 0.2 M and inhibitory effect in the concentration b...
متن کاملSaccharomyces cerevisiae TFS9, a novel isolated yeast capable of high caffeine-tolerant and its application in biodecaffeination approach
There is a great call for using microbial bio-decaffeination approach to remove caffeinefrom caffeinated products and industrial wastes. We aimed in this study to screen strainsof yeasts which exhibit high caffeine tolerance and to investigate the bio-degradation ofcaffeine under growth conditions. Sixteen yeast strains were isolated from the cultivatedtea soils collected from sites of northern...
متن کاملIsolation of indigenous Glutathione producing Saccharomyces cerevisiae strains
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 frui...
متن کاملIsolation and Identification of Yeast Strains Capable of Producing Single Cell Protein from Whey in Co-Cultures with Saccharomyces cerevisiae
In this study, twenty-five whey samples collected from dairy industries in the city of Isfahan. The sampleswere cultured on malt extract broth (MEB) and yeast extract glucose chloramphenicol agar (YGCA) media.Eleven yeast strains (designated M1 to M11) were isolated from the culture. The strains were identified bytheir morphological and physiological properties. Betagalactosid...
