Endospora Bakteri

The bacterial endospore is a special, resistant, dormant structure formed by some bacteria, which enables them to resist harsh environmental conditions

Endospore formation (sporulation) normally commences when growth ceases because of lack of nutrients; it is a complex, multistage process

Transformation of dormant endospores into active vegetative cells is also a complex, multistage process that includes activation (preparation) of the endospore, germination (breaking of the endosporeís dormant state), and outgrowth (emergence of the new vegetative cell)
