Abstract:
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.
