Which aseptic control technique is most effective in destroying all micro organisms including spores and viruses?

The most effective aseptic control technique for destroying all microorganisms, including spores and viruses, is sterilization through autoclaving. This process utilizes high-pressure steam at temperatures typically around 121°C (250°F) for a specific duration, effectively killing all forms of microbial life. Other methods, such as ethylene oxide gas and dry heat sterilization, can also achieve similar results, but autoclaving is widely regarded for its efficiency and reliability in various settings.
