Percentages of L. monocytogenes (open bars) and S. enterica (filled bars) biofilm cells in the dual-species sessile community remaining viable (A) and killed (B) following a 6-min exposure to the following disinfectants: BC at 50 ppm, NaClO at 10 ppm, PA at 10 ppm, and HP-PA at 5 ppm each. Control treatment is without disinfection. Dual-species biofilms were initially left to be formed on SS coupons incubated for 144 h in TSB at 15°C (with medium renewal every 48 h).
