A comparative study of the lipid bilayer phase status and structure of the outer membrane of free-living Bradyrhizobium strain 359a (Nod(+)Fix(+)) and 400 (Nod(+)FixL) or Rhizobium leguminosarum 97 (Nod(+)Fix(+), effective) and 87 (Nod(+)FixL, ineffective) has been carried out. Also, the effect of the symbiotic pair combination on the lipid bilayer structure of the bacteroid outer membrane and peribacteroid membrane, isolated from the nodules of Lupinus luteus L. or Vicia faba L., has been studied. As a result, it is shown that the lipid bilayer status of the bacteroid outer membrane is mainly determined by microsymbiont, but not the host plant. In the contrast, the lipid bilayer status of the peribacteroid membrane and, as a consequence, its properties depend on interaction of both symbiotic partners.
对自由生活的慢生根瘤菌菌株359a（结瘤（+）固氮（+））和400（结瘤（+）固氮L）或豌豆根瘤菌97（结瘤（+）固氮（+），有效）和87（结瘤（+）固氮L，无效）的外膜脂质双层相状态和结构进行了比较研究。此外，还研究了共生对组合对从白羽扇豆或蚕豆根瘤中分离出的类菌体外膜和类菌体周膜脂质双层结构的影响。结果表明，类菌体外膜的脂质双层状态主要由微共生体决定，而非宿主植物。相反，类菌体周膜的脂质双层状态及其性质取决于两个共生伙伴的相互作用。
