Why You Should Test Autoclave Efficiency Using Geobacillus stearothermophilus
Geobacillus stearothermophilus is a thermophilic bacterium whose highly resistant spores are used to test autoclave sterilization efficiency. Its spores survive extreme heat due to molecular defenses, making them ideal biological indicators. Proper autoclave validation requires biological indicators rather than relying solely on gauge readings or chemical indicators to ensure complete sterilization in medical and laboratory settings.
