[Biosynthesis of sterols by various yeasts]

Biosynthesis of sterines by yeasts was studied with 112 strains belonging to 9 genera; 77 strains synthesized ergosterine and 15 most active strains were selected, which belonged to the following genera: Saccharomyces, Torulopsis, Hanseniaspora, Debaryomyces, Candida, Mechnikowia. Sterine composition was studied in these active strains. The main sterine in all studied strains was ergosterine.
