Abstract
Hydroxylated diether lipids are the most abundant lipids in Methanosarcina acetivorans, Methanosarcina thermophila, and Methanosarcina barkeri MS and Fusaro, regardless of the substrate used for growth. Structural analysis of the lipid moiety freed of polar head groups revealed that the hydroxydiether lipids of all the Methanosarcina strains were hydroxylated at position 3 of sn-2 phytanyl chains. The finding that Methanosarcina strains synthesize the same hydroxydiether structure suggests that this is a taxonomic characteristic of the genus. Methanococcus voltae produced minor amounts of the 3-hydroxydiether characteristic of Methanosarcina spp. and also the 3'-hydroxydiether described previously for Methanosaeta concilii.
