Overview

  • Caloranaerobacter azorensis is a Gram-negative, non-spore-forming, 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 27%. Caloranaerobacter azorensis is unlikely to be a gut coloniser. (Wery2001)



  • This organism has been recovered from a deep-sea hydrothermal vent. 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. Likely to be transient and not a long-term gut commensal.
    • QUIRKS
  • No growth at 37C, so unlikely to be a gut coloniser.
