This work is devoted to the study of the antimicrobial activity of strains of lactic acid bacteria isolated from the phyllosphere of fruit trees. 81 strains from the genera Lactobacillus, Streptococcus, Leuconostoc, Pedicoccus and Peptococcus were used against test cultures of opportunistic gram-positive (Staphylococcus aureus, Bacillus subtilis), gram-negative (Escheriachia coli, Pseudomonas aeruginosa, Klebsiella pneumoniae) and Candida tropicalis fungi. In relation to all test cultures, strains from the genera Lactobacillus and Streptococcus showed the highest antimicrobial activity. Strains from the genera Leuconostoc and Pedicoccus showed high antimicrobial activity against gram-negative bacteria, strains from the genus Peptoccocus showed high antimicrobial activity against gram-positive bacteria and the fungus Candila tropicalis. The test culture of Klebsiella pneumoniae showed the highest sensitivity to strains of all genera of lactic acid bacteria.

Keywords:strains of lactic acid bacteria, gram-positive and gram-negative bacteria, antimicrobial activity, Candila tropicalis.
