Abstract

In this study, cellular lipid compositions of two mesophilic sulfate-reducing bacteria were analyzed by high performance liquid chromatography-mass spectrometry (HPLC-MS). In Desulfosarcina variabilis and Desulforhabdus amnigenus, alkylether-containing phospholipids were detected which had previously only been found in significant amounts in deeply branching hyperthermophilic bacteria and archaea. Combining information from HPLC-MS analysis and chemical degradation experiments, ether lipids were identified as 1-alkyl-2-acyl-phosphatidyl ethanolamines, glycerols and cholines. In Desulforhabdus amnigenus, n-penta-, n-hexa- and n-heptadecyl ethers were present (in order of decreasing abundance), whereas Desulfosarcina variabilis solely contained n-hexadecyl ether side chains.
