Differing from the growing cells,the spore with unbelievable resistance to external environment changes could survive for a long period,in which the unique structures and chemical compounds play a vital role.The coats provides a barrier against lytic enzymes,toxic chemicals,the inner membrane retards the influx of toxic chemicals into the core,the core’s low water content protects against wet heat and likely plays an important role in DNA photochemistry,α/β-type SASP accounts for the wet heat,UV resistance as well as ionizing radiation,and the core DPA affects the wet heat resistance and DNA’s UV photochemistry.
