Obtaining of spheroplasts in nodule bacteria of lucerne, clover, bean and pea
- All-Union Research Institute of Agricultural Microbiology
A simple universal procedure has been developed for obtaining stable spheroplasts from the fast-growing species of Rhizobium (R. meliloti, R. phaseoli, R. trifolii, R. leguminosarum). Spheroplasts were prepared by culturing cells in the osmotically stable medium with a decreased content of calcium cations in the presence of penicillin, followed by treatment with lysozyme. The electron-microscopic analysis of the process of spheroplasts formation was performed. The average effectiveness of the cell wall regeneration is 1.4-5.0 %.
