Overview

  • Pelobacter propionicus is a Gram-negative, non-spore-forming, strictly anaerobic, non-motile, rod-shaped bacterium. It has been detected in at least 1 gut microbiome compilation study or metastudy. The DNA G+C content is 57.4%. Pelobacter propionicus is probably a rare gut coloniser. (Schink1984)



  • This organism has been recovered from anoxic muds of freshwater origin; sewage sludge digesters, Germany. 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.
