[Influence of aerobic and anaerobic conditions on the chemical composition and enzyme activity of the buds of mother cells of Candida utilis IBFM-405 yeasts]

Abstract

The effect of aerobic and anaerobic conditions on the chemical composition and enzyme activity of buds and mother cells of yeast Candida utilis IBPM-405 was studied. Upon transition from aerobic to anaerobic conditions buds and mother cells of yeast Candida utilis IBPM-405 showed significant changes in the qualitative composition of exchange pool of free intracellular amino acids and quantitative content of its individual components. The transition did not influence the amino acid composition of proteins. Upon the transition from aerobic to anerobic conditions the activity of phosphorylase, glucose-6-phosphatase andn glutaminase in mother cells increased and in buds decreased, inadequate changes in the activity of aminoacyl-tRNA-syntheses occurring.
