Methods of destroying bacterial spores

The spores of Bacillus spp. are found widely distributed in nature, which may cause contamination of the environment and eventually diseases to humans and animals. The formation of the bacterial spore is a sophisticated mechanism by which some bacteria remain viable inadequate when subjected to survival stress such as lack of nutrients. The spores are highly resistant to heat, radiation, various disinfectant and antiseptic agents that routinely destroy bacteria in vegetative form. The inactivation of bacterial endospores has been regarded as a challenge for human health, environmental quality and food safety.
