Overview

  • Syntrophococcus sucromutans is a Gram-negative, non-spore-forming, strictly anaerobic, non-motile, coccus bacterium. The DNA G+C content is 52%. Syntrophococcus sucromutans is probably a rare gut coloniser. (Krumholz1986)



  • This organism has been recovered from mesophilic, anaerobic, microbial ecosystems where complex organic matter is degraded. 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.
