Antimicrobial activity of L. mesenteroides P45 against enteropathogenic Escherichia coli, Salmonella enterica serovar Typhimurium, S. enterica serovar Typhimurium and L. monocytogenes. Upper panel cell-to-cell antimicrobial effect of a lawn of strain P45. Middle panel 100 µL of cell-free, neutralized and 2× concentrated supernatant. Bottom panel cell-to-cell antimicrobial effect of a lawn of EPS-producing P45 grown on APT + 20 % sucrose. Mean ± SD inhibition zones (mm) observed for upper panel were: 11.75 ± 1.26, 11.25 ± 1.73, 9.25 ± 0.82, 10.5 ± 1.63, for each assayed bacteria, respectively. For middle panel: 7.5, 6.7 ± 0.5, 6.5 ± 0.58, 9.0 ± 1.15, respectively. Values of inhibition zone in EPS-producing cell-to-cell assays are omitted because the heterogeneous shape of the lawn of strain P45 (bottom panel)
