How do high temperatures kill bacteria?
High temperatures do not always kill bacteria. In fact, some do well for themselves by living in an environment that kills other life forms. They are happy to live in places like deep sea vents and the hot springs of Yellowstone. But they are adapted to this extreme lifestyle.
Bacteria are killed by heat because, simply put, heat denatures the proteins (and enzymes) they need to live. Proteins must retain their structure in order to function properly. Heat breaks the bonds that allow them to keep their correct shape.
However, at high temperatures, any bacteria die) there is even a method of steoylization by fire
