How to Survive Hunger? Sporulation is the Bacterial Answer.

by Yaroslava Polosina 
Bacteria same as multicellular organisms like us often meets unpleasant or even deadly conditions in their life. Dryness, cold, heat, poison, and most often the absence of nutrition can easily kill the bacterial population. To survive severe conditions bacteria developed different approaches, and the main and most efficient of them is sporulation. We find out what are the spores, how bacteria produce them, and what is their role in the maintenance of the bacteria population.
