The standard practice is 121-degrees Celcius (250-degrees Fahrenheit). But it is not the heat alone that destroys the bacteria. Autoclaves also work under tremendous pressure (15psi or greater). It is the combination of heat and pressure that destroys the Bacteria.

Actually, the reason that the temperature of autoclaves (which heat at 121C) is so high is that it's designed to inactivate highly heat-resistant spores. Most vegetative cells are inactivated at lower temperatures (less than 100C); the temperature depends on the genus and species of the organism.

At 163* for 20 seconds- in Fluids
At higher temperatures as the thickness & viscosity increases.
Pathogens are killed normally.
BUT, there are certain THERMOPHILIC ORGANISMS & spores, which may survive even boiling.
To make bacteria-free, you need to AUTOCLAVE for 30 minutes.
