title: Multiply methyl-branched fatty acids and diacids in the polar lipids of a microaerophilic subsurface microbial community.
abstract: A previously unreported series of di- and tri-methylated fatty acids, as well as saturated and monounsaturated diacids were identified in polar lipids isolated from environmental subsurface sediment samples. Mechanisms are proposed for their formation, but their origin and role in cell membranes remains unknown.
