Biochemical characteristics of yeast.Peer-reviewed article

T. GINOVA-STOLJAVOVA

Some theoretically and practically significant biochemical properties of two Saccharomyces carlsbergensis strains were followed, e. g. aerobic growth and respiration in 2 % and/or 0,15 % glucose medium and fermentation activity in 2 % maltose + 10 % glucose medium. In contrast to strain No. 51, which shows on the glucose medium diauxic growth with 5 h rest, low respiration activity and, if grows on maltose, sensibility to glucose effect, strain T showed properties very exceptional for S. carlsbergensis: this strain has grown aerobically on glucose without diauxic effect and with relatively high respiration activity to the Q O₂ as measured with Warburg's manometric apparatus. Fermentation activity of strain T on maltose was relatively high, too (when measured Q N₂ CO₂) and it was not influenced significantly even after adding glucose. The author emphasizes importance of the metabolism control analysis for the brewing bottom yeast evaluation and their selection from the point of view of low sensibility toward dextrose effect.
