The aim of this study is to search for promising strains of bacteria to create new biological products. New bacteria were isolated from wheat grains and identified by 16 S rRNA sequencing as Bacillus sp. L1 and Panaebacillus sp. L2. The cytokinin-producing bacteria Bacillussp.L 1 increased the length of the roots of plants by 70 %, the mass of roots by 17 %. N-fixing Panaebacillus sp. L2 increased the root length by 39 % and the mass by 27 %. The results of vegetation experiments on growing wheat of the ‘Leningradskaya 6’ variety under controlled conditions showed an increase in wheat productivity by 15.6 % when inoculated with Bacillus sp. L1 and by 31.2 % when inoculated with Panaebacillus sp. L2. Preliminary results of vegetative experiments indicate that Bacillus sp. L1 and Panaebacillus sp. L2 can be used as an active components of biological products to increase wheat productivity.
