Rhizosphera’s bacteria as antagonists of patogenic and opportunistic microorganisms

The comparing research has been realized to study antagonistic effect of microorganisms, which was associated with plants. Staphylococcus aureus and Escherichia coli was used as test-microorganisms. It has established that antagonistic effect has been explored at Pseudomonas fluorescens and Bacillus subtilis, which have been isolated from plants of studied families. Pathogenic and opportunistic bacteria have sensitiveness to associative microbes which was expressed with supression of growth. The results of research would be basis for work out of new methods of struggle with pathogenic microflora of plants which have practical using. The studied stains of rhizobacteria would be using for making of modern biopreparats to defend plants.
