ISOLATION OF ACTINOMYCETES WITH ANTAGONISTIC ACTIVITY AGAINST GRAM-NEGATIVE PHYTOPATHOGENIC BACTERIA
Abstract
Twenty eight actinomycetes cultures were isolated as separate colonies from phyto material of fruit trees with visual signs of bacterial infection and soil samples of Minsk region. The isolates were screened for antagonistic activity against plant pathogens from a specialized depository of phytopathogenic microorganisms Belarusian Collection of Non-Pathogenic Microorganisms (BIM). Two groups of actinomycetes cultures with antibacterial activity against phytopathogenic microorganisms of species Pseudomonas corrugata and Pseudomonas syringae were selected. In the short-term perspective, these strains may become the basis of “biorational” pesticides to control plant diseases.
