The viability and symbiotic properties of active strain Bradyrhizobium japonicum 46 after its long-term storage using different methods were studied. It was established that strain storing in evaporative freezing conditions as well at periodic passages the strain preserves its ability to form active symbiosis with soybean plants. Long-term storage under the layer of mineral oil had negatively influenced on the symbiotic properties of B. japonicum 46 strain resulted in only partial restoration of strains virulence, nitrogen fixing activity and competitiveness.
