The polar lipid composition of Mesorhizobium ciceri.
The extractable lipid composition of Mesorhizobium ciceri strain HAMBI 1750 grown in a phosphate sufficient medium (79CA) is reported. Cardiolipin (CL-27% of total lipids), phosphatidylglycerol (PG-18%), phosphatidylethanolamine (PE-1%), phosphatidylcholine (PC-30%) and two methylated derivatives of PE, i.e. phosphatidyl-N, N-dimethylethanolamine (DMPE-1%) and phosphatidyl-N-monomethylethanolamine (MMPE-1%), were found to make up the phospholipids of the analysed bacteria. Nonphosphorus, ornithine-containing lipid (OL-10%) was also detected. Polar groups of phospholipids were predominantly acylated with cis-11,12-methyleneoctadecanoyl (lactobacillic) residues, whereas the ornithine lipid contained mainly 3-hexadecanoyloxy-11,12-methyleneoctadecanoic acid bound to the alpha-amino group.
