Many bacteria, such as Clostridium, can form endospores (a dormant stage that allows them to survive adverse conditions for a while), such as , which allow them to survive boiling water. Autoclaves use a temperature of 121 degrees C to be sure to kill all endospores and any other possible contaminants.
