The significant role of spore formation in the reproductive cycle of this bacterium would be to allow the bacteria to survive in extreme conditions. The spore formed is called an endospore which is a thick cover made of protein. These spores are mostly resistant to heat and chemicals which makes the bacteria survive in harsh conditions. Spores can only be destroyed by sterilization and it require very high pressures and very temperatures. In microbiology and medical settings, this process is usually done in a device known as the autoclave. Sterilization is a process that involves the killing of all microorganism in a system whether it is harmful or beneficial.
