Abstract excerpt
Bacillus cereus is a ubiquitous endospore-forming bacterium, which mainly affects humans as a food-borne pathogen. Bacillus cereus can contaminate groundwater used to irrigate food crops.

Our results showed that vegetative B. cereus cells rapidly evolved in a mixed population composed of...
