Overview

  • Anaerotignum propionicum, (aka Clostridium propionicum), is a Gram-positive, spore-forming, strictly anaerobic, motile, rod-shaped bacterium. It has been detected in at least 2 gut microbiome compilation studies or metastudies. The DNA G+C content is 36%. Anaerotignum propionicum is probably a rare gut coloniser. (Ueki2017; Cardon1946; Rainey2011gBergey)



  • This organism has been recovered from black mud. KS24 - a closely related bacterium (S16 94%) - was detected in human faeces (probably transient). 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.
