[Isolation and phenotypic characteristics of growth-stimulating rhizobacteria (PGPR), with high root-colonizing and phytopathogenic fungi inhibiting abilities].
Some bacterial strains isolated from the plant rhizosphere showed high root-colonizing ability and antiphytopathogenic activity against 6 fungal species. The antifungal activity was species-specific, which could be accounted for by the fact that the isolates differed in the ability to produce lytic enzymes (chitinases, proteases, and lipases) and to secrete cyanide. The possibility of using there rhizobacteria to control phytopathogens is discussed.
