Abstract：AIM:To study the bactericidal efficiency and possible bactericidal mechanism of strong acid electrolyzed water (SAEW)and alkaline electrolyzed water (AEW)on Enterococcus faecalis (E. faecalis)biofilm. METHODS:The E. faecalis biofilm on coverslips was cultured and treated by 52.5 g/L NaClO(control),SAEW and AEW respectively.The effects were examined by the viable cell count method and the morphological change of E. faeca-lis was observed by scanning electron microscopy. RESULTS:The bactericidal efficiency of SAEW and 52.5 g/L NaClO showed no significant difference(P＞0.05). SAEW showed greater bacterial reduction than AEW(P＜0.05). But after treatment,the trend of the time-dependent curves and the morphological change were similar among the 3 preparations. CONCLUSION:Both SAEW and AEW had bactericidal efficiency to E. faecalis. And the bactericidal mechanism was similar to that of NaClO.
