Antibacterial activity of cecropin 3 or lebocin. A After each treatment, the representative LB agar plates showed the S. aureus or E. coli colonies. Either S. aureus or E. coli were incubated with H2O, BSA1 (25 μM), BSA2 (100 μM), cecropin 3 (25 μM), or lebocin (100 μM) at 25 °C with agitation for 1 h. The mixture was diluted and plated onto the LB agar plates. B-F The number of S. aureus (B), E. coli (C), A. johnsonii (D), S. rhizophila (E), and E. ludwigii (F) colonies after each treatment was determined. Bacterial growth was exhibited as the ratio of viable colonies against the H2O control group. BSA was incubated as a control. The data were analyzed using one-way ANOVA followed by Tukey’s multiple comparison test. The different characters above the bars represent significant differences
