Antagonistic effect of lactic acid bacteria on Salmonella in co-cultures |
The purpose of the research was to estimate the influence of lactic acid bacteria on pathogenic bacteria of Salmonella Senftenberg W775. The method of co-cultures was applied in order to examine the interaction between the investigated microorganisms. The results obtained indicate that 3 LAB strains (numbers 2, 3, 4) isolated from fermented plant material indicated high antibacterial activity against Salmonella rods. The growth of the pathogen in associated cultures was completely inhibited in 48 hours. The theoretical survival of Salmonella incubated in the presence of Lactobacillus plantarum was significantly longer and amounted to 132 hours. None of the LAB strains examined was influenced by Salmonella rods. |
