[Role of biocompatible adhesives in the increase of rhizobia physiological activity and productivity of soybean-rhizobia symbiosis].

On the basis of natural exopolysaccharide xanthan and exopolyacrylamide the sticky-gene composition has been developed. Addition of that composition to the culture medium provided a 26.3 times higher viability of Bradyrhizobium japonicum UCM B-6035 cells during its storage. Introduction of plant growth regulators biosil or ivin into this composition increased the survival of rhizobia. Application of gel inoculant B. japonicum favored more intensive growth of rhizosphere microorganisms, nutrient's accumulation in the soil and increased productivity of soybean-Rhizobium symbiosis.
