What could be the possible reason of high resistance provided by endospore formation?
The mechanisms that account for this resistance include the impermeability of the endospore coat, the dehydration of the cytoplasm and the production of special proteins that protect the spore's DNA. The center of the endospores contains the core and it consists of the cytoplasm, DNA, ribosomes, enzymes and everything that is needed to function once returned to the vegetative state. The core is dehydrated, which is essential for heat resistance, long-term dormancy and full chemical resistance. Calcium dipicolinate is a major component of the core and has been shown to play a role in resistance to wet heat and UV light.
