Abstract
The content of total lipid as well as of ergosterol, squalene, and maj or fatty acids were compared in the cells of a distillery strain of Sa ccharomyces cerevisiae incubated for 3, 48 and 120 h in the presence o f 5, 10 and 15 % ethanol. Ethanol induced lipid accumulation with pref erential ergosterol biosynthesis. The relative contents of palmitic an d stearic acid decreased whereas the amount of palmitoleic and oleic a cid increased. The total content of all fatty acids rose as a conseque nce of the ethanol treatment.
