[Lipids and lipases of various yeasts]

Optimal conditions for accumulation of lipids and glycogen, and for biosynthesis of lipase, were found to be similar in Candida, Rhodotorula, Lipomyces, and Cryptococcus yeast cultures. Fractional composition of their lipids and prevailing fatty acids were also similar. However, in cultures of the Candida genus, contrary to cultures of other genera, acids with the number of carbon atoms below 14 and above 20 have not been identified. Maxima in the dynamics of biosynthesis of lipids and lipase by Candida cultures did not coincide. Lipids isolated from yeast cells were hydrolysed by lipases of Candida, Rhodotorula, Lipomyces, and Cryptococcus at a higher rate than olive oil.
