Study Notes
Temperatures and Spore-Forming Microbes
- 121 °C (249.8 °F) is the minimal temperature that can kill spore-forming microbes. This temperature is used in autoclaves, which are high-pressure steam sterilizers.
- Temperatures below 121 °C (249.8 °F) are NOT sufficient to kill all spore-forming microbes.
- Spore-forming microbes begin to die at temperatures above their optimal growth range, but they can survive at temperatures as high as 100 °C (212 °F) for short periods.
- 121 °C (249.8 °F) is the most effective temperature against spore-forming microbes, as it ensures their complete destruction.
- Temperatures below 121 °C (249.8 °F) are considered safe for spore-forming microbes, allowing them to survive.
