Characterization of the antimicrobial activity of alcohol-NaCl spray against non-spore forming bacteria. (a) MRSA, (b) P. aeruginosa, (c) E. coli MG1655, and (d) alcohol-resistant E. coli. (i) IPA-NaCl solution and (ii) EtOH-NaCl solution; mean ± SD, n = 3. *: below detection limit. Bacterial suspensions in DI water were sprayed onto Petri dishes (4.14 ± 0.8 mg/cm2) and left to dry for one hour at room temperature (RT). Following spraying with alcohol-NaCl solution (4.14 ± 0.8 mg/cm2), bacteria were eluted at each time point (5, 10, and 30 min) for time-dependent viability measurement. The y-axis represents CFU/µg protein, and the x-axis represents time (min). 0 min represents the initial bacterial suspensions.
