The neutral lipids and phospholipids of two strains of rhizobia in their free-living state and in symbiosis with a host plant are described. The principal lipid classes found were the polymer poly-beta-hydroxybutyrate, phospholipids, free fatty acids, glycerides, methyl esters, aliphatic alcohols, and hydrocarbons. The lipids include unusual unsaturated methyl-branched and saturated methoxy-branched fatty acids. Most components were found to be common to both forms of both strains, although the proportions varied. A number of strain differences could be discerned.
本文描述了两株根瘤菌在自由生活状态以及与宿主植物共生状态下的中性脂质和磷脂。所发现的主要脂质类别包括聚合物聚-β-羟基丁酸酯、磷脂、游离脂肪酸、甘油酯、甲酯、脂肪醇和碳氢化合物。这些脂质包含不寻常的不饱和甲基支链脂肪酸和饱和甲氧基支链脂肪酸。虽然比例有所不同,但大多数成分在两株根瘤菌的两种状态下都是共有的。可以辨别出一些菌株差异。
