摘要：

Glycerol-derived membrane lipids are essentially absent in the thermophilic bacterium Thermomicrobium roseum. A series of straight chain and internally methyl-branched 1,2-diols of carbon numbers C18 to C23 were found to replace glycerolipids in this bacterium. Fatty acids were present but were ester-linked to the diols or amide-linked to polar heads groups and not to glycerol. This thermophile has evolved the integration of diols as a novel approach for the construction of its cytoplasmic membrane.
