Bacillus is a genus of endosporing Gram-positive rods with a regular shape. They are often isolated from soils, but some strains inhabit human skin. They are chemoheterotrophs and ferment sugars to lactic acid. Some strains are pathogenic, including B. anthracis (anthrax) and B. cereus (gastroenteritis). Some strains of Bacillus produce antibiotics.
