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(More)
In order to investigate the effects of Ecovital complex biological formulation on soybean, we carried out the field experiments on gray forest soil, Kiev region and on chernozem, Cherkassy region, under natural conditions. Our results showed that Ecovital application (co-inoculation with Bradyrhizobium and Bacillus strains) significantly improves soybean(More)
The activity of key enzymes of ammonium assimilation in cell-free extracts of soybean rhizobia characterized with different effectiveness in symbiosis, has been researched. It has been found out that at highly efficient strain Bradyrhizobium japonicum UKM B-6035 the most active links in the system of ammonium assimilation reactions are glutamate synthase(More)
