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.
Endospore-forming bacteria are characterized by the location (position) of the endospore in the mother cell (sporangium) before its release. The spore may be central, terminal or subterminal, and the sporangium may or may not be swollen to accommodate the spore.he two medically-important genera are Bacillus, the members of which are aerobic sporeformers in the soils, and Clostridium, whose species are anaerobic sporeformers of soils, sediments and the intestinal tracts of animals.
