Methyl-branched fatty acids form > 92% of the total fatty acid component of the cells, with 12-methyltetradecanoic (anteiso-C15), 13-methyldecanoic (iso-C15) and 14-methylhexadecanoic
(anteiso-C17) as the major components. Straight chain fatty acids generally account for 1% of the total fatty acids, and unsaturated fatty acids are not detected at all
