Clostridium butyricum is obligate anaerobic, Gram-positive, spore-forming rod bacterium. Cells are rod-shaped, motile, and peritrichously flagellated. C. butyricum is named for its capacity to produce high amounts of butyric acid. Several strains of C. butyricum have been described in a variety of environments and are common human and animal gut commensal bacteria. C. butyricum is found in the feces of 10-20% of healthy humans. They are important bioproduction microbial genus bacteria, and non-toxigenic strains present potential as the probiotics.
