Overview
Bacillus species are mostly non-pathogenic, environmental organisms.
Characteristics
The bacteria are large, motile, Gram positive rods that produce endospores. They are aerobes or facultative anaerobes and are catalase positive and oxidase negative. They grow on non-enriched media. Bacillus anthracis colonies are up to 5mm diameter, flat, dry and grey with a ground-glass appearance. Curled outgrowths from the edge of the colony give a 'medusa head' appearance. They are non-haemolytic and can be differentiated from Bacillus cereus, as B.cereus is a beta-hemolytic bacterium. Bacillus licheniformis forms dull, rough, wrinkled colonies, with hair-like outgrowths. Bacillus species can often tolerate adverse environmental conditions.
