Abstract
  • The lipid composition of the extremely halophilic bacterium Salinibacter ruber (Bacteroidetes) was investigated by thin layer chromatography, gas chromatography, high performance liquid chromatography and electrospray ionization-mass spectrometry. Polar lipids represent about 80% of the total lipid extract. The main polar lipids are a sulfonic acid analogue of ceramide (or capnine analogue), phosphatidylcholine, phosphatidylserine, dimethylphosphatidylethanolamine, phosphatidylglycerol, cardiolipin or bisphosphatidylglycerol, and a glycolipid. The major acyl chains in the phospholipids are C16:1 Delta9cis and C18:1 Delta11cis, while the sulfonolipid contains an amide-bound iso C15:0 fatty acid. On changing the salinity of the culture medium, no significant differences were found in the lipid profile or the unsaturation of the lipid fatty acyl chains. The structure of the cardiolipin, which represents 20% of polar lipids, has been elucidated by gas chromatography and electrospray ionization mass spectrometry analysis. (literal)
