Changes in survival rate enzyme activities and in Escherichia coli with ozone

With ozone, it is important to know the decomposition of cell components in order to explain the bactericidal effects. We chose Escherichia coli as a bactericidal model with ozone and observed the changes in activities of alkaline phosphatase and β-galactosidase, located in the periplasm and cytoplasm, respectively. The activity of β-galactosidase more rapidly than that of alkaline phosphatase in cells. In addition, we present an equation to describe our results.
