摘要：

The ergosterol ester fraction of Saccharomyces cerevisiae has been analyzed following a variety of incubation conditions. Free fatty acids were obtained after saponification of the sterol ester fraction and were analyzed gas chromatographically. Cells grown under anaerobic conditions showed a maximal rate of synthesis of sterol esters at 48 hours. Under aerobic incubation conditions, maximum sterol esterification was seen at 12 hours. Esters of C16 and C18 fatty acids are the predominant ones, followed by those of C14 acids. The rates of synthesis of free sterol and sterol esters follow similar patterns. © 1969.
