Effects of bacteriocin-like inhibitory substance (BLIS) on bacteria membrane permeability of S. aureus (A) and P. aeruginosa (B) by PI staining, and the morphology of S. aureus (C) and P. aeruginosa (D) observedby SEM analysis after 24 h treatments. PBS and 1% SDS were considered negative and positive control, respectively, for PI staining. The yellow arrows indicate intracellular debris released from cells or damaged cells due to the pore formation in bacterial cell walls. Error bars represent the standard deviation of triplicates. *, p < 0.05; ***, p < 0.001; ****, p < 0.0001; ns, no significant difference
