Endospores are dormant alternate life forms produced by the genus Bacillus, the genus Clostridium, and a number other genera of bacteria, including Desulfotomaculum, Sporosarcina, Sporolactobacillus, Oscillospira, and Thermoactinomyces.
Endospores are formed by vegetative bacterial cells in a process called sporillation. Only one spore can be formed per bacterial cell, which can be formed in about eight hours and remain dormant for many years until the right environment triggers the cell to become active again. Some Bacteria make exospores or cysts instead of endospores but are not as resistant to harsh conditions. To watch step by step endospore formation please use following link: http://www.microbelibrary.org/images/Gauthier/Endopore_formation.htm. Endospores are green, vegetative (non endospore bacteria) cells are red.
