Overview

  • Desulfitobacterium hafniense, (aka Desulfitobacterium frappieri), is a Gram-negative, spore-forming, strictly anaerobic, motile, rod-shaped bacterium. It has been detected in at least 8 gut microbiome compilation studies or metastudies. The DNA G+C content is 46-47%. Desulfitobacterium hafniense is probably a common, although minor, coloniser of the gut. (Bouchard1996; Niggemyer2001)



  • This organism has been recovered from human faeces, and anaerobic 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.
