摘要
The composition of membrane phospholipids in exponential-and stationary-phase cells of Azospirillum brasilense was studied. The total content of membrane phospholipids made up about 7% of dry cell mass and was almost independent of the growth phase. Exponential-phase bacteria contained phosphatidylethanolamine (64.4%), phosphatidylglycerol (19.5%), cardiolipin (9.2%), phosphatidic acid (5.1%), and phosphatidylinositol (1.8%). In the stationary phase, the phospholipid composition was qualitatively the same, although somewhat changed quantitatively.
