New rhizosphere herbicide-degrading strains capable of biocontrol of phytopathogenic microorganisms

Biotechnologically significant strains of bacteria of the Pseudomonas genus have been isolated from the rhizosphere of wild and cultivated cereals. The isolated strains are able to biocontrol the phytopathogenic fungi and bacteria and degrade the herbicide glyphosate as the only source of phosphorus (P. chlororaphis subsp. chlororaphis G16, P. chlororaphis subsp. aureofaciens G27, P. protegens G23-4) and the herbicide Axial as the only carbon source (P. chlororaphis G27). These strains exhibit lipolytic and proteolytic activities and P. chlororaphis G27 can also produce hydrogen cyanide, which has an antifungal effect. The studied strains can be useful as the basis of biopreparations for protecting plants from phytopathogenic microorganisms and treating soils polluted with herbicides.
