[The antagonistic activity of spore bacteria in relation to representatives of the genus Erwinia].
Strains of 26 species of genus Bacillus were examined for an antagonistic effect relative to erwiniosis agents: Erwinia amylovora, Erwinia carotovora, Erwinia chryzanthemi, Erwinia herbicola, Erwinia rhapontici. The Erwinia strain growth seized in the process of combined cultivation with microbes-antagonists. Practically all the studied strains of bacteria of genus Erwinia were sensitive to these or those Bacillus cultures. A considerable number of Erwinia strains studied were sensitive simultaneously to several cultures of Bacillus subtilis. The mechanism of action of antagonistic substances excreted by a definite strain of B. subtilis and damaging cells of bacteria of the Erwinia genus is studied. A damage of K+ ions' transport via cell walls of sensitive phytopathogenic bacteria after treatment of their cells with filtrates of culture liquid of active B. subtilis strain is found.
