Abstract
The lipid composition of Roseiflexus castenholzii, a thermophilic filamentous phototrophic bacterium related to uncultivated filamentous phototrophic bacteria that predominate in hot spring microbial mats, is reported. R. castenholzii lipid extracts were dominated by components characterized by alkane-1-ol-2-alkanoate moieties glycosidically bonded to a C6 sugar. Similar fatty glycosides, with an additional
