Bacterial Endospores

When faced with starvation, Bacillus and Clostridium species undergo sporulation - a developmental program producing highly resistant endospores. The process involves asymmetric cell division, engulfment of the forespore, and synthesis of protective coat layers. Spores can survive extreme heat, radiation, desiccation, and chemicals for centuries.
