Concept
Autoclave and moist heat
Pressurized steam sterilization
AW-toh-klayv
High-yield clue
Standard steam sterilization is about 121 degrees C at ~15 psi for roughly 15 minutes, which even endospores cannot survive.
Overview
An autoclave sterilizes with pressurized saturated steam, and moist heat kills microbes by denaturing proteins more efficiently than dry heat. It is the reference standard for destroying even resistant endospores.
Classification
- Microbial-control concept
- Moist-heat sterilization
- Pressurized saturated steam
Lab & identification clues
- Moist heat denatures proteins faster than dry heat at the same temperature
- Geobacillus stearothermophilus spores serve as a biological indicator
- Pressure raises steam temperature above 100 degrees C
Associations
- Reference standard for endospore destruction
- Contrasted with dry-heat oven vocabulary
- Biological/chemical indicators verify the process
Commonly confused with
- Moist heat vs dry heat
- Autoclave vs pasteurization
