摘要

本研究主要探討電解法二氧化氯溶液對噬菌體MS2與其宿主細胞大腸桿菌(Escherichia coli BCRC 50354)之殺菌效果。經不同濃度與pH值之二氧化氯溶液對噬菌體F-specific bacteriophage (MS2)及其宿主細胞大腸桿菌(E. coli BCRC 50354)進行處理，實驗結果顯示134.00 ppm濃度之二氧化氯溶液對F-specific bacteriophage (MS2)具有顯著之殺菌效果，然而對宿主細胞大腸桿菌(E. coli 50354)之抑菌率則約爲83.7%。此外，當溶液酸鹼值介於6.0~8.0之間，二氧化氯溶液對F-specific bacteriophage (MS2)及宿主大腸桿菌(E. coli BCRC 50354)皆具有穩定之殺菌效果。

In this study, the disinfection efficiency of chlorine dioxide solution prepared by electrolysis method on the F-specific bacteriophage MS2 and its host bacteria (Escherichia coli BCRC 50354) was evaluated under various concentrations and pH values. The results showed that the killing effect of chlorine dioxide solution at the concentration of 134.00 ppm on MS2 phage is apparently efficiency However, the disinfection rate of chlorine dioxide solution at the concentration of 134.00 ppm on E. coli is about 83.7% In addition the MS2 phage and E. coli were constantly killed off by chlorine dioxide solution under the range of pH value from 6 to 8.
