Popis: This study aimed to compare the plasma-activated water (PAW) and plasma-activated microbubble water (PAMBW) with commercial sodium hypochlorite (SH) for postharvest processing of fresh-cut romaine lettuce. The PAW and PAMBW properties showed that PAMBW produced higher content and more effective reactive oxygen and nitrogen species than PAW. PAMBW treatment recorded a 4.6 log10 CFU/g Escherichia coli (E. coli) O157:H7 reduction on lettuce compared to a 3.2 log10 CFU/g reduction by SH. Field emission scanning electron microscopy (FE-SEM) and qRT-PCR revealed that the reactive species generated by PAMBW treatment damaged the E. coli O157:H7 cell membranes and significantly (P
