Overview


  • Clostridium aurantibutyricum is a Gram-positive, spore-forming, strictly anaerobic, motile, rod-shaped bacterium. The DNA G+C content is 27%. Clostridium aurantibutyricum is probably a rare gut coloniser. (Hellinger1947; Rainey2011aBergey)



  • This organism has been recovered from human faeces (Rainey2011aBergey), rotting vegetation and sewage sludge. The risk classification (www.baua.de) for this organism is 1, i.e., low risk of infection and spread. Pathogenicity status unknown, or very unlikely to be pathogenic. Is a known gut commensal. Robust growth can have positive consequences for gut health.
