Overview

  • Saccharofermentans acetigenes is a Gram-positive, spore-forming, strictly anaerobic, non-motile, oval-shaped bacterium. It has been detected in at least 1 gut microbiome compilation study or metastudy. The DNA G+C content is 55.6%. Saccharofermentans acetigenes is unlikely to be a gut coloniser. (Chen2010)



  • This organism has been recovered from sludge treatment, China. Pathogenicity status unknown, or very unlikely to be pathogenic. A possible gut commensal.
    • QUIRKS
