In vitro time-kill assessment of the bactericidal activity of Mul-1867 and CHG against bacterial biofilms. Kill curves of (a, b) S. aureus, (c, d) E. coli biofilms exposed to various concentrations (0.05 and 2 %) of either Mul-1867 or CHG for various durations (15, 30, and 60 s) are shown. The antiseptic inhibitory effect on biofilms was assessed by measuring the number of CFU obtained after antibiotic treatment. All experiments were performed in triplicates
