Determination of the antimicrobial activity of lactic acid bacteria isolated from the Black sea mussel Mytilus galloprovincialis Lamarck, 1819

The present study reports on the determination of antimicrobial activity lactic acid bacteria (LAB) isolated from Black sea mussel Mytilus galloprovincialis Lamarck, 1819. samples were collected in period August 2018 until March 2021. BIOLOG system was used for microbiological determination. From M. Lam. four species LAB - Sporolactobacillus kofuensis , Lactobacillus sakei Streptococcus gallolyticus ss and Lactibacillus brevis . strains determined against test cultures ( Escherichia coli 3398 Staphylococus aureus 745 Bacillus subtilis 6633 Salmonella typhimurium 3591 Listeria monocytogens 863 Enterobacter aerogenes 3691 Aspergillus niger Penicillium claviforme Saccharomyces cerevisae Candida albicans 8673 glabrata 72 ). Before analysis activity, cultured media with different concentrations sugars 2, 5 10%. results showed that 4 S. L. glucose oligosaccharides completely lost their all studied variants. Therefore, some carbohydrates (glucose) induce synthesis outside cell biologically active molecules, which can probably be attributed to peptides/proteins.
