Summary Introduction
Introduction:
Bacteria such as Clostridium, Cacillus, and Clostridium produce endospores, which are dormant bodies. These bacteria have a two-phase life cycle, a vegetative cell and endospores. The process of endospores formation in bacteria takes place during challenging environmental conditions and is called “sporulation”. The process in which endospores go back to its vegetative state is called germination.
