Overview

  • Herminiimonas contaminans is a Gram-negative, non-spore-forming, facultatively anaerobic, motile, rod-shaped bacterium. It has been detected in at least 1 gut microbiome compilation study or metastudy. The DNA G+C content is 55.4%. Herminiimonas contaminans is likely to be transient and not a long-term gut coloniser. (Kampfer2013a)



  • This organism has been recovered from human faeces and contaminated biopharmaceuticals. Pathogenicity status unknown, or very unlikely to be pathogenic. A possible gut commensal.
    • QUIRKS
  • Can't grow at 37C, so unlikely to be a gut coloniser.
    • GENERAL CHARACTERISTICS (Kampfer2013a);
    Character Response
  • 🌡
  • Temperature tolerance:
  • grows at 15℃; doesn't grow at 37℃; Grows optimally at 25-30℃.
  • ⥅
  • Substrates assimilated or utilised:
  • acetate; fumarate; lactate; malate; propionate; oxoglutarate;
  • Active enzymes:
  • Ala arylamidase; catalase; oxidase;
    • SPECIAL FEATURES
    Character Response
  • ✗
  • Nitrate:
  • not reduced
