title: Systematic study of the 3-hydroxy fatty acid composition of mycobacteria.
abstract: Twenty-seven strains belonging to 12 Mycobacterium species were studied for 3-hydroxy fatty acid composition. Mycobacterial cells were subjected to both mild and strong acid methanolysis, after which the liberated hydroxy fatty acids were purified and analyzed by gas chromatography-mass spectrometry as methyl ester trimethylsilyl ether derivatives. Altogether, 21 3-hydroxy fatty acids containing 14 to 28 carbon atoms were detected; 10 were straight chain, 6 were 2-methyl branched chain, and 5 were 2,4,6-trimethyl branched chain. The mycobacterial strains were classified in groups according to 3-hydroxy fatty acid patterns.
