What Causes Bacteria to Sporulate?

Sporulation is a drastic response undertaken by some bacteria, mostly Firmicutes, in response to extreme stress. During sporulation, the growing cell (also referred to as a vegetative cell) will forego normal cellular division to instead form an endospore

endospore
An endospore is a dormant, tough, and non-reproductive structure produced by some bacteria in the phylum Firmicutes. ... In endospore formation, the bacterium divides within its cell wall, and one side then engulfs the other. Endospores enable bacteria to lie dormant for extended periods, even centuries.

What might cause a bacteria to sporulate?

Essentially, sporulation refers to the formation of spores from vegetative cells during unfavorable environmental conditions. As such, it may be described as an adaptive response that allows the organism to survive given adverse conditions (radiation, extreme heat or cold, lack of nutrition etc).

How long does it take for bacteria to sporulate?

In rich medium, B. subtilis cells divide by binary fission approximately every 30 minutes. By contrast, deterioration of environmental conditions triggers sporulation, a developmental process that takes about 8 to 10 hours.
