Ozone inactivation of bacteria is always carried out very quickly. Unlike other biocides: ozone can react with the bacterial cell wall lipid double bond, penetrate into the interior of the bacterium, the role of proteins and lipopolysaccharides, change the permeability of the cell, thus leading to bacterial death. Ozone also acts on the nuclear material in the cell, such as purines and pyrimidines in nucleic acids to destroy DNA.
2 ozone inactivation mechanism of viruses:
Ozone's effect on viruses is first of all the four polypeptide chains of the viral capsid protein of the viruses, and make the RNA is damaged, especially the proteins that form it. Phage oxidized by ozone, electron microscopic observation is visible in its epidermis was broken into many fragments, from which many ribonucleic acids are released, interfering with its adsorption to the host body. The thoroughness of ozone sterilization is not to be doubted.
