ABSTRACT
The strains of soybean nodule bacteria (n = 140) were allocated from the nodules of soybean which grew up on six soil types. For the first time the strains with intensive growth have been discovered among the microsymbionts of soybean. It is established that these strains were highly specific for the host-plant, but were different in morphology, growth-rate, accumulation of the extracellular polysaccharides, antibiotics sensitivity and ability for using carbohydrates. Properties of these strains did not change after the repeated passage through a host-plant. The similarity in fatty acids spectra is marked for the strain with the intensive growth KB1-1 and slow-growing strains 6346 and KC2-3. Quantitative and qualitative differences in monosaccharides structure of EPS of investigated strains are revealed. Presence ofxylose (2.7%) and the raised contents of rhamnose (18.4%) is differentiated from EPS of strain KB1-2 and EPS of strains KC2-3 and 6346. The paper is presented in Ukrainian.
