Fig 1. Antibiofilm activities of BmKn‒2 peptide and its derivatives against P. aeruginosa.

Bacterial cells were incubated with BmKn‒2 peptide and derivatives at the final concentration of 800 μM. After incubation at 37°C for 24 h, biofilm biomass was assessed by crystal violet staining assay and OD measured at 550 nm. Data are expressed as mean ± SEM of three independent experiments. *, P < 0.05 and **, P < 0.01 compared with the untreated control. A dot black line represents an OD cut-off value.
