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.
Since they're commonly called spores, some people think that bacterial endospores are associated with bacterial reproduction. Really, creation of an endospore is a survival mechanism used by bacteria to withstand harsh environmental conditions. Bacteria propagate when times are good. When times are bad, certain bacteria have the capability to shrink down and encrust critical cellular elements in a tough casing.
