Yeast strains Cryptococcus albidus, Cryptococcus laurentii, Rhodotorula minuta were isolated from a moss sample. Candida oleophila and Rhodotorula mucilaginosa were isolated from a soil sample taken from Livingston Island. Antarctica. Fatty acid, phospholipid, sterol and tocopherol composition was determined in separated lipid fraction after fermentation in a medium containing glucose, peptone and yeast extract. Unsaturated fatty acids, mainly oleic (51-65%) and linoleic (9.5-16.8%), predominated in triacylglycerols. Sterols represent ca. 120-930 mg per kg dry biomass. The content of major phospholipids (phosphatidylcholine, phosphatidylinositol and phosphatidylethanolamine) was ca. 100-800 mg/kg. The amount of tocopherols (mainly gamma- and delta-tocopherol) was 2.1-6.3 mg/kg.
从一份苔藓样本中分离出了浅白隐球菌、罗伦隐球菌和微小红酵母菌株。嗜油假丝酵母和粘红酵母是从南极利文斯顿岛采集的一份土壤样本中分离出来的。在含有葡萄糖、蛋白胨和酵母提取物的培养基中发酵后，对分离出的脂质部分测定了脂肪酸、磷脂、甾醇和生育酚的组成。三酰甘油中主要是不饱和脂肪酸，主要为油酸（51 - 65%）和亚油酸（9.5 - 16.8%）。甾醇含量约为每千克干生物量120 - 930毫克。主要磷脂（磷脂酰胆碱、磷脂酰肌醇和磷脂酰乙醇胺）的含量约为100 - 800毫克/千克。生育酚（主要是γ - 和δ - 生育酚）的含量为2.1 - 6.3毫克/千克。
