Abstract
The article considers the possibilities of solubilization of silicon, potassium and phosphorus in the presence of bacteria of the genus Pseudomonas spp. and Bacillus spp. isolated in pure culture from the microflora of bottom silt deposits. As a result of the analysis of semi-quantitative solubilization of Si, P and K using Alexandrov’s agarized medium, 15 strains were tested. Of the studied strains, only three strains of the genus Bacillus spp. caused simultaneous extraction of Si, P and K. The obtained primary data can be used in biotechnological production of bacterial fertilizers and optimization of the technology of bioconversion of bottom silt deposits.
