Overview


  • Caldicellulosiruptor diazotrophicus is a Gram-positive, non-spore-forming, short rod-shaped bacterium. It has been detected in at least 1 gut microbiome compilation study or metastudy. The DNA G+C content is 34.8%. Caldicellulosiruptor diazotrophicus is unlikely to be a gut coloniser. (Chen2021)



  • This organism has been recovered from Nakabusa hot springs, Japan. Pathogenicity status unknown, or very unlikely to be pathogenic. Likely to be transient and not a long-term gut commensal.

  • QUIRKS
  • Optimum growth temperature is 70C, so likely not a gut coloniser.
