The primary action responsible for killing microorganisms during the steam sterilization process is condensation. In steam sterilization, moist heat is used to achieve sterilization, and the condensation of steam onto cooler surfaces is critical for effective microbial inactivation. When steam comes into contact with the cooler instruments or materials being sterilized, it condenses, releasing latent heat. This transfer of heat raises the temperature of the items being sterilized and inactivates microbial cells, leading to their destruction.

This process is efficient because the heat generated through condensation quickly penetrates the materials, ensuring that the entire load reaches the necessary temperature for the appropriate amount of time to achieve sterility. The effectiveness of steam sterilization lies in its ability to rapidly transfer heat to the items, allowing for thorough and consistent sterilization.

In contrast, the other methods mentioned—convection, alkylation, and oxidation—are either less relevant in the context of steam sterilization or pertain to different sterilization techniques. Convection refers to the movement of heat through fluid, and while it plays a role in heating, it is not the primary action at work during steam sterilization. Alkylation is a mechanism used in ethylene oxide sterilization, and oxidation pertains to sterilization methods using chemical
