Overview

  • Butyricicoccus faecihominis is a Gram-positive, non-spore-forming, strictly anaerobic, non-motile, coccus bacterium. It has been detected in at least 3 gut microbiome compilation studies or metastudies. The DNA G+C content is 55.6%. Butyricicoccus faecihominis is probably a rare gut coloniser. (Takada2016)



  • This organism has been recovered from human faeces (Takada2016). Pathogenicity status unknown, or very unlikely to be pathogenic. A possible gut commensal.
    • GENERAL CHARACTERISTICS (Takada2016);
    Character Response
  • H+
  • Acid from carbohydrates usually produced:
  • glucose;
  • Active enzymes:
  • alkaline phosphatase; acid phosphatase; Leu arylamidase;
    • SPECIAL FEATURES (Takada2016);
    Character Response
  • ✓
  • Metabolites produced:
  • formate (minor); butyrate (major); CO₂; H₂; indole;
  • ✗
  • Metabolites not produced:
  • H₂S;
  • NOTES

    Pure cultured Butyricicoccus faecihominis sp. nov. did not
    grow with mucin, indicating that this species cannot utilize
    mucin. Moreover, 16 carbohydrates were used, and it was
    determined that the species had almost no enzymes related
    to carbohydrate metabolism. L-Fucose was also not utilized.
    Nevertheless, the novel species was culturable by mucin
    enrichment culture. These results indicate that the novel
    isolate may have used the mucin degradation products produced
    by the mucin-degrading bacteria in faeces.
