The fractional composition of lipids was studied in 32 yeast strains belonging to the genera of Rhodotorula Harrison, Lipomyces Lodder et Kreger van Rij and Cryptococcus Kutz. The effect of C/N ratio in the growth medium on the content of various lipid fractions was studied. Lipids of the most studied cultures were found to contain di- and triglycerides, waxes, free fatty acids, sterines, their esters, and phospholipids. The fraction of monoglycerides was also detected in Rhodotorula and three species of Cryptococcus, but not in Lipomyces and Cr. laurentii. If C/N ratio equals 10, the predominant lipid component in Lipomyces is triglycerides, and in Rhodoturula and Cryptococcus phospholipids. The fraction of triglycerides prevailed in all cultures at C/N ratio of 100. The content of phospholipids decreased with an increase of C/N ratio in the medium from 10 to 100.
对属于红酵母属（哈里森）、油脂酵母属（洛德和克雷格·范·里伊）和隐球菌属（库茨）的32株酵母菌株的脂质组成进行了研究。研究了生长培养基中碳氮比对各种脂质组分含量的影响。发现大多数研究培养物的脂质含有甘油二酯和甘油三酯、蜡、游离脂肪酸、甾醇、它们的酯以及磷脂。在红酵母属和三种隐球菌中也检测到了甘油单酯部分，但在油脂酵母属和罗伦隐球菌中未检测到。如果碳氮比等于10，油脂酵母属中主要的脂质成分是甘油三酯，而在红酵母属和隐球菌属中是磷脂。在碳氮比为100时，所有培养物中甘油三酯部分占主导。随着培养基中碳氮比从10增加到100，磷脂含量下降。
