Overview

  • Anaerotignum neopropionicum, (aka Clostridium neopropionicum), is a Gram-negative, spore-forming, strictly anaerobic, motile, rod-shaped bacterium. It has been detected in at least 1 gut microbiome compilation study or metastudy. The DNA G+C content is 34.5%. Anaerotignum neopropionicum is probably a rare gut coloniser. (Ueki2017; Tholozan1992)



  • This organism has been recovered from anoxic digester 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. A possible gut commensal.
