SAHW was sprayed in a box for indicated periods (3, 5 or 7 min). Subsequently, the lids of the dishes that contained bacteria on either glass plates or rayon sheets were removed, and the bacteria were exposed to SAHW for 5 min. a) Reduction factor (RF)=log₁₀ (titer of control/ml) −log₁₀ (titer of treated samples/ml). b) Spraying times. c) Data represent means ± standard deviation of three different experiments.
