Bacillus subtilis became the most s

Bacillus subtilis became the most studied species In the genus, Bacillus due to its natural competence for uptake of extracellular ONA that facilitates simple genetic modification and occurrence of sporulation, one of the first studied bacterial cell differentiation processes. The dormant spores can survive harsh circumstances (high temperature, desiccation, UV, and y-radiation), predation by microorganisms and macroorganlsms, or even extraterrestrial conditions. B. subtilis can be isolated from various environments, from soil to marine habitats, and utilized in various applications from enzyme production and food fermentation to plant biocontrol.
