Overview

  • Nautilia nitratireducens is a Gram-negative, non-spore-forming, strictly 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 36.0%. Nautilia nitratireducens is likely to be transient and not a long-term gut coloniser. (PerezRodriguez2010)



  • This organism has been recovered from a deep-sea hydrothermal vent. Pathogenicity status unknown, or very unlikely to be pathogenic. A possible gut commensal.
    • QUIRKS
  • Optimum growth temperature is 55C so unlikely to be a gut coloniser. Can use thiosulfate, sulfur and nitrate as terminal electron acceptors.
