Abstract
The fatty acid composition from mycelia of Streptomyces hygroscopicus strains was studied. A significant proportion of C-18:2 was found in c ultures. High levels of C-16:0, iso-C-16:0 and C-18:1 were also detect ed in all S. hygroscopicus strains. The different representatives of S . hygroscopicus had almost the same proportion of unsaturated fatty ac ids. Certain shifts in the amount of iso, anteiso and straight-chain f atty acids in some cultures were revealed. This might be explained by the adaptation capability of strains belonging to one species to form a variety of available fatty acids determined by particular cell membr ane composition favouring certain antibiotic biosynthesis.
