In this study, the antimicrobial effect of ozonized water was investigated in the DSM2500-SK environmental decontamination vehicle. Following a biological attack, rapid and timely decontamination would prevent the spread of contamination and reduce the extent of damage. The antimicrobial effect of ozonized water was investigated on some bacteria such as Pseudomonas aeruginosa (peripheral bacteria), Staphylococcus aureus (gram-positive bacteria), Escherichia coli (gram-negative bacteria) and Bacillus subtilis (spores), according to the existing standards. In the first step the sensitivity of bacteria was determined by the modified microdilution method by minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) of ozonized water and in the next step the concentration of the ozonized water affecting bacteria was investigated. Rising temperatures, impurities and pH cause the instability of ozonized water. The results showed that the minimum lethal dilution of bacteria by ozonized water at a concentration of 3 ppm was 7.5×104 for Staphylococcus aureus, 7.5×105 for Pseudomonas aeruginosa, and 7.5×105 CFU/mL for Escherichia coli O157 and this disinfectant solution has no effect on bacterial spores. For the determination of the effective concentration of ozonized water on bacteria, it was found that the outlet of 100% concentrated ozonized water is capable of disinfection.
