The anti-biofilm activity of bacteriocin-like inhibitory substance (BLIS) extracted from CYLB30 (A) and CYLB47 (B). Five pathogenic bacteria, including Salmonella enterica serovar Choleraesuis, K. pneumoniae, P. aeruginosa, E. faecium, and S. aureus, were treated with BLIS. After crystal violet staining, the biofilm was dissolved in absolute ethanol and measured by OD590nm. Error bars represent the standard deviation of triplicates. The biofilm formation of pathogens was compared to a negative control without BLIS treatment (TSB group). *, p < 0.05; ***, p < 0.001; ****, p < 0.0001; ns, no significant difference
