Preliminary Evaluation on Germicidal Efficacy of the Electrolyzed Oxidizing Water

Xiaodong Yu

Abstract

A quantitative suspension test was used for detecting the germicidal efficacy of EOW against Staphy auseus,Esche- richia coli and spores of Bacillus subtilis var.niger.This test was also used for observing the influence of 10% bovine serum on efficacy of EOW in killing Staphy aureus.It was found that EOW with 2 minutes contact time could attain a kining rate of 99.99% for S.aureus and E.coli.As the suspension of S.aureus containing or not containing 10% bovine serum,EOW with 20 minutes contact time could attain a killing rate of 57.11% or 100% respectively.EOW can rapidly kill or destory the S.aureus,E.coli.The 10% bovine serum has significant influence on germicidal efficacy of EOW.
