What degrees Celsius is the steam sterilization biological indicator incubated?

The steam sterilization biological indicator is incubated at temperatures between 55 and 60 degrees Celsius to effectively promote the growth of any surviving microorganisms after the sterilization process. This temperature range is optimal for detecting the viability of the spores used in the biological indicator, which typically include highly resistant bacteria such as Bacillus stearothermophilus. Incubating at this temperature allows for accurate results that determine whether the sterilization process has been successful and ensures the safety and sterility of surgical instruments. The other temperature ranges suggested do not provide the optimal conditions for spore growth needed to confirm the efficacy of the steam sterilization process.
