Strongly acidic Denkaisui[electrolyzed water], its chemically mimic solution and their derivative solutions with different available chlorine concentration(ACC) and pH were examined for the chemical species as the bactericidal basis by checking the bactericidal activity against Bacillus subtilis. The following were obtained. 1) The bactericidal activity correlated with available chlorine concentration and no substantial difference was observed in the bactericidal activity of the Denkaisui and its mimic solution. 2) Major chemical basis for the bactericidal activity is ACC as the HOCl form. 3) pH shows the indirect effect that controls the ratio of HOCl in ACC in spite of no obviously direct bactericidal effect. 4) Oxidation-reduction potential(ORP) plays no substantial role as the direct bactericidal factor. 5) Free radicals are not contributive as the original basis for the bactericidal effect of the Denkaisui.
