[Group and fatty acid composition of the lipids in yeasts of the genus Candida].

The group and fatty acid composition of lipids from 62 species and strains of Candida yeast was investigated. No strict correlation between the group composition of lipids and the yeast species was found but certain consistencies were seen. For instance, C. humicola yeast showed a higher ability for biomass and lipid accumulation. In their group composition triglycerides were predominant while polar lipids + monoglycerides and sterol esters + hydrocarbons were in small quantities as compared to other yeast species. Besides, C. humicola yeast contained no pigments. The C. guilliermondii strains contained low amounts of free fatty acids. The lipid fraction of all C. tropicalis yeast studied contained pigments. The yeast with increased amounts of triglycerides showed a comparatively high content of biomass and lipids. C. guilliermondii yeast had a high content of oleic acid and a low content of linoleic acid. All the yeast contained small quantities of stearic acid.
