测定了 C.crescentus CB13 和 CB15 的磷脂组成。酸性磷脂、磷脂酰甘油和心磷脂约占总磷脂的 87%。未检测到磷脂酰乙醇胺及其前体磷脂酰丝氨酸。 C.crescentus CB13 的外膜和内膜被分离，磷脂分析揭示了两膜中磷脂酰甘油和心磷脂相对含量的异质性。正如其他细菌膜的情况所示，当细胞培养物进入稳定期时，心磷脂的浓度增加而磷脂酰甘油减少。
The phospholipid composition of C. crescentus CB13 and CB15 was determined. The acidic phospholipids, phosphatidylglycerol and cardiolipin, comprise approximately 87% of the total phospholipids. Neither phosphatidylethanolamine nor its precursor phosphatidylserine was detected. The outer and inner membranes of C. crescentus CB13 were separated, and phospholipid analysis revealed heterogeneity with respect to the relative amounts of phosphatidylglycerol and cardiolipin in the 2 membranes. As was shown to be the case for other bacterial membranes, the concentration of cardiolipin increases and phosphatidylglycerol decreases as cell cultures enter stationary phase.
