[Fatty acid composition of Fusidium coccineum lipids].

The fatty acid composition of the lipids synthesized de novo or during growth of the organism producing fusidic acid, Fusidium coccineum on complex media was studied. The content of the total extractable lipids in the mycelium did not exceed 10-11 per cent ty the biomass dry weight. Unsaturated fatty acids with 18 carbon atoms in the chain, mainly oleinic and linoleic acids and saturated fatty acids such as palmitic and stearic acids predominated. The ratio of the main fatty acids and the content of the minor acids were subject to strains and conditions of their cultivation. However, linoleic and oleinic acids predominated in all the lipids except the lipids from submerged cultures growing in the form of unusually large clots. Such lipids contained up to 60 per cent of palmitic acid.
