Overview

  • Chloracidobacterium thermophilum is a Gram-negative, Unknown, microaerophilic, non-motile, rod-shaped bacterium. The DNA G+C content is 61.3%. Chloracidobacterium thermophilum is unlikely to be a gut coloniser. (Tank2015; Bryant2007)



  • This organism has been recovered from a geyser sprint, Yellowstone National Park, USA. Pathogenicity status unknown, or very unlikely to be pathogenic. Likely to be transient and not a long-term gut commensal.
    • QUIRKS
  • Cells have chlorosomes used for photosynthesis. High minimum growth temperature suggests it is not a gut coloniser
