Final answer:
Microbial kill in the Ozone sterilizer is achieved through a process called oxidation.
Step-by-step explanation:
The process through which microbial kill in the Ozone sterilizer is achieved is called oxidation. Ozone is an unstable molecule that readily gives up one atom of oxygen, providing a powerful oxidizing agent that is toxic to most waterborne organisms. It works by oxidizing and breaking down the cellular components of microorganisms, effectively killing them.
