Bacillus

(genus Bacillus), any of a group of rod-shaped, gram-positive, aerobic or (under some conditions) anaerobic bacteria widely found in soil and water. The term bacillus in a general sense has been applied to all cylindrical or rodlike bacteria. The largest species are about 2 mm (micrometres; 1 mm = 10-6 m) across by 7 mm long and frequently occur in chains. Bacillus species form dormant spores
