Bacillus stearothermophilus

Bacillus stearothermophilus is a type of bacteria that thrives in high-temperature environments, such as hot springs or heated canned foods. It is known for its ability to form heat-resistant spores, which protect it from extreme conditions. This bacterium is often used in sterilization testing because its spores can survive standard sterilization processes, helping scientists ensure that items like medical equipment or food packaging are free of harmful microbes. While harmless to healthy individuals, its presence indicates the effectiveness of sterilization methods in controlling microbial contamination.
