The phospholipid composition of Bradyrhizobium spp

The phospholipid composition of two strains of Bradyrhizobium is reported. In contrast to previous studies, we determined that phosphatidylglycerol is a major phospholipid within this bacterial genus. Furthermore, neither phosphatidylserine nor phosphatidylinositol was detected within lipid extracts...

Description
Summary:The phospholipid composition of two strains of Bradyrhizobium is reported. In contrast to previous studies, we determined that phosphatidylglycerol is a major phospholipid within this bacterial genus. Furthermore, neither phosphatidylserine nor phosphatidylinositol was detected within lipid extracts derived from these bacteria. In addition to phosphatidylglycerol, other major phospholipids of Bradyrhizobium were shown to include phosphatidylcholine, phosphatidylethanolamine, and cardiolipin. Possible explanations for the discrepancies between the present study and those of previous investigations are discussed.
