The bacteria of <em>E. italicus</em> ONU547 strain showed antagonistic activity against the plant pathogens <em>Rhizobium radiobacter</em> C58 and <em>Erwinia carotovora</em> ZM1 <em>in vivo</em> causing 33.3 and 24.8% of inhibition, respectively, and formed the biofilm of middle level on the plant roots. The consortia of enterococci bacteria with <em>L. plantarum</em> showed in most cases higher antagonistic activity and ability to biofilm formation. Bacterial consortia of all used lactic acid bacteria strains showed the highest antagonistic activity against <em>R. radiobacter</em> causing 77.7% of inhibition. Besides this consortium, the phytopathogen <em>E. carotovora</em> was inhibited preferably by the mixture of enterococci with <em>L. plantarum</em> ONU311 (33.3% of inhibition). It has been shown that high adhesive properties and/or competition for nutrients could be the mechanism of inhibitory activity of bacteria of <em>E. italicus</em> ONU547 strain against plant pathogens, whereas the antagonistic activity of their consortia with lactobacilli can be explained, in addition, by the action of organic acids.</p&gt;}, number={2}, journal={The Journal of V.N.Karazin Kharkiv National University.
