Survival of S. aureus biofilm cells after 5 min of exposure to 0, 5, 250, 500, and 5,000 mg of BAC per liter in two separate experiments (open and solid bars) and survival of S. aureus phase 1 test suspension cells exposed to 5 mg of BAC per liter (gray bar) (separate results, taken from reference 27). The values are averages for at least four coupons. The error bars indicate standard deviations. An asterisk indicates that the level of survival was below the detection limit (0.01%).
