| Abstract: | An aminolipid from Chlorobium limicola f. thiosulfatophilum has been purified and characterized by thin-layer chromatography, infrared specroscopy, 1H-NMR, 13C-NMR, plasma desorption mass spectrometry, and fast atom bombardment mass spectrometry. The structure is that of an aminosugar (neuraminic acid) attached to a sphingosine backbone with one myristic acid linked to the sphingosine by an amide bond. Related glycosphingolipids and capnoids are found in the Bacterioides/Flavobacteria which are related to the green sulfur bacteria by the criterion of 16S rRNA structure. No aminoglycosphingolipid was found in Chloroflexus aurantiacus. |
