N2 - Antibacterial activity of probiotic enterococci is often related to the production of bacteriocins. There is a variety of Enterococcus faecium strains which synthesise one or several enterocins including A, B, P, 96, L50AB and others. In this work we have analysed the probiotic strain E. faecium L3 whose genome contained the genes encoding enterocins А, В and a three-component regulatory system. All these genes were found to be expressed in enterococcal strain L3. Antimicrobial activity of the strain tested on the strains of Listeria monocytogenes and Streptococcus agalactiae was pheromone dependent. Chemically synthesised cyclic peptides (analogues and shorter derivates of EntF) with different molecular structures were able to increase the antagonistic activity of the strain E. faecium L3 in contrast to the strain E. faecium SF68, which does nоt have genes encoding enterocins А and В.
