Pistacia terebinthus Resin as Yeast Immobilization Support for Alcoholic Fermentation

Alcoholic Fermentation without Yeast Cells*

Until now it has not been possible to separate fermenting activity from living yeast cells; the following describes a procedure that solves this problem. One thousand grams of brewer’s yeast1 that had been cleaned as a prerequisite for the preparation of compressed yeast, but to which no potato starch had been added, is carefully mixed with the same weight of quartz sand2 and 250 g Kieselguhr. ...

Obtaining Yeast Cultures for Alcoholic Fermentation from Lyophilized Strains Saccharomyces

NIKOLOVA , R., Tsv. TSVETKOV and T. DONEV, 2008. Obtaining yeast cultures for alcoholic fermentation from lyophilized strains Saccharomyces. Bulg. J. Agric. Sci., 14: 16-21 The objective of the present study is to obtain yeast cultures for alcoholic fermentation from lyophilized strains Saccharomyces with high number of viable cells. Two types of strains of brewer’s yeasts – the strain Saccahar...

Germination studies on pistacia terebinthus

Why, when, and how did yeast evolve alcoholic fermentation?

The origin of modern fruits brought to microbial communities an abundant source of rich food based on simple sugars. Yeasts, especially Saccharomyces cerevisiae, usually become the predominant group in these niches. One of the most prominent and unique features and likely a winning trait of these yeasts is their ability to rapidly convert sugars to ethanol at both anaerobic and aerobic conditio...

Characteristics of Different Brewer’s 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...
