Abstract
The bactericidal effects of high concentrations of airborne ozone were tested against Escherichia coli and Staphylococcus aureus. Petri dishes containing the microorganisms were inserted in a chamber and exposed for 10-480 seconds to ozone concentrations between 300 and 1500 ppm. Death rates in excess of 99.99% were achieved for both species. The mechanism of inactivation accorded with the predictions of first- and second-order kinetics, suggesting that the disinfection action of ozone in air parallels the action of ozone in water.
