Investigation of the Effective Concentration of Ozonated Water for Disinfection in the Presence of Protein Contaminants.

Ozonated water (OW) is presently used as a chemical disinfectant in many fields, due to its versatile antimicrobial properties. As ozone rapidly decomposes to oxygen, especially in the presence of organic matter, it is important to estimate the authentic antimicrobial activity of OW in the presence of contaminants. However, the effect of contaminants on the antimicrobial activity of OW has not been fully investigated.
