[The fatty acid composition of total lipids and triglycerides in several actinomycetes]

Saturated and unsaturated fatty acids (C13-C18) have been found in the composition of lipids and triglycerides of actinomycetes by GLC. Qualitative composition of fatty acids was identical on chemically defined and organic media. Synthesis of unsaturated fatty acids by the actinomycetes was intensive (total yield over 50% and even 84.2% in Act. canosus) on the organic medium I which may be recommended for production of lipid fractions with elevated content of unsaturated fatty acids.
