Antibacterial activity and mechanism of slightly acidic electrolyzed water (SAEW) combined with ultraviolet light against Staphylococcus aureus

This study aimed to investigate the antibacterial effect and mechanism of Staphylococcus aureus (S. aureus) by combined treatment with slightly acidic electrolyzed water (SAEW) and ultraviolet light (UV, 253.7 nm) (SAEW + UV). The result shows that about 6.70 logs CFU/mL of S. aureus was inactivated...

Description
Summary:This study aimed to investigate the antibacterial effect and mechanism of Staphylococcus aureus (S. aureus) by combined treatment with slightly acidic electrolyzed water (SAEW) and ultraviolet light (UV, 253.7 nm) (SAEW + UV). The result shows that about 6.70 logs CFU/mL of S. aureus was inactivated after the SAEW + UV treatment (available chlorine concentration, ACC, 70 mg/L) for 90 s. The SAEW + UV treatment has a higher antimicrobial effect than UV or SAEW alone treatment, and the effect increases with time and ACC (P
