Description
The bacillus lives in soils worldwide at moderate temperatures. It can be grown in aerobic or anaerobic conditions (it is a facultative anaerobe) in a medium with essential nutrients, including carbon and nitrogen sources. In 1877, this organism was the first to be shown to cause disease by Robert Koch and verified by Louis Pasteur.
