AquaROS disinfection of E. coli and S. typhimurium. Wet samples were prepared by inoculating sterile stainless-steel discs with 5 μl bacteria sample. Dry samples were prepared in the same manner but followed with 5 min of drying under house vacuum. After spraying, serially diluted samples were spot plated (5 μl each) onto LB agar plates for E. coli and LB agar-streptomycin plates for S. typhimurium. Each bar represents one standard deviation from three replicates.
