Bacilli are an extremely diverse group of bacteria that include both the causative agent of anthrax (Bacillus anthracis) as well as several species that synthesize important antibiotics. Under stressful environmental conditions, the cells bring on egg-shaped endospores that can bide inactive for extended periods. These characteristics originally defined the genus, but not all such species are closely related, and many have been locomoted to other genera. In addition to medical uses, bacillus spores, due to their uttermost permissiveness to both heating and disinfectants, are used to test heat sterilization techniques and chemical disinfectants. Bacilli are also expended in the detergent cooking up industriousness for their ability to synthesize important enzymes.
Bacillus is a genus of Gram-positive, baculiform bacteria and a member of the division Firmicutes. Bacillus species can be obligate aerobes or facultative anaerobes, and test positive for the enzyme catalase. Ubiquitous in nature, Bacillus includes both free-living and pathogenic species.
Bacillus thuringiensis (Bt) is an insecticide with fantastical dimensions that come through utile for pest control in certain situations. Bt is a naturally occurring bacterium common in soils throughout the world. Several strains can infect and kill insects. Because of this property, Bt has been developed for insect control. At confront, Bt costs the only "microbial insecticide" in widespread use.
