Overview

  • Hydrogenoanaerobacterium saccharovorans is a Gram-negative, non-spore-forming, strictly anaerobic, non-motile, rod-shaped bacterium. It has been detected in at least 3 gut microbiome compilation studies or metastudies. The DNA G+C content is 41.9-42.8%. Hydrogenoanaerobacterium saccharovorans is probably a rare gut coloniser. (Song2009)



  • This organism has been recovered from human faeces, and an anaerobic digester. Pathogenicity status unknown, or very unlikely to be pathogenic. A possible gut commensal.
