The autoclave should sterilize b. stearothermophilus pretty well.
The autoclave tape typically contains heat-sensitive indicator ink that changes color when exposed to high temperatures achieved during autoclaving. It is not a microorganism.
The cardinal temperatures of Bacillus stearothermophilus are typically around 45-55 degrees Celsius for the minimum, 60-70 degrees Celsius for the optimum, and 70-80 degrees Celsius for the maximum temperature for growth.
Geobacillus stearothermophilus spores are commonly used for testing the efficiency of an autoclave. These spores are resistant to high temperatures and can be used as a biological indicator to ensure that the autoclave is properly sterilizing equipment.

Most likely intended as a variation of Bacillus stearothermophilus which is a Bacillus that can survive very high temperatures.However in the question, since b in the word bacillus is in a lower case, it may refer to any rod shaped bacteria and thermophilus implies heat tolerance. These include several Bacillus sp., Thermus thermophilus, Alicyclobacilli, Lactobacillus acidophilus or bulgaricus (not extremophiles, but can survive a little heat), and others. New ones are frequently discovered.
An Autoclave is a piece of equipment used for sterilization purposes and requires quarterly calibration. There are three types of calibrations to be done - timer, temperature and pressure. To calibrate the timer, post an appropriate correction factor directly on the autoclave. Post a correction factor on the autoclave control panel if the temperatures were different, and for pressure post a correction factor on the autoclave if it is not true.
Survival of Bacillus spores, particularly Bacillus stearothermophilus, is used as an index of sterilization because these spores are highly resistant to heat and other sterilization methods. Their resilience makes them ideal biological indicators to test the efficacy of sterilization processes. If the spores survive, it indicates that the sterilization conditions were inadequate, while their destruction confirms that the process was effective. This reliability ensures that sterilization protocols are properly validated in healthcare and laboratory settings.
Stearothermophilus is a thermophilic bacterium that requires oxygen for its metabolic processes. The exact amount of oxygen it needs can vary depending on factors such as growth conditions and environment. Generally, stearothermophilus would require a sufficient supply of oxygen to support its metabolic activity.

Thermus aquaticus is a bacterium with a wide temperature tolerance, capable of surviving in temperatures ranging from 50°C to 80°C. It is known for its heat-resistant enzymes and is commonly used in molecular biology techniques like polymerase chain reaction (PCR).
Autoclave - album - was created in 1991.
