Abstract
Bacillus species are Gram positive, aerobic heterotrophs, ubiquitous bacteria, characterized by their ability to form resistant spore coats. There are about 48 known species in the genus Bacillus but only B. anthracis and B. cereus are associated with human disease. Bacillus species are mesophilic bacteria that produce heat-resistant endosopores with a growth range of 10°C to 48°C, with optimal growth at 28°C to 35°C. In addition, they can grow in a broad pH range of 4.9 to 9.3.
