Overview

  • Crassaminicella thermophila is a Gram-positive, spore-forming, anaerobic, motile, rod-shaped - curved bacterium. It has been detected in at least 1 gut microbiome compilation study or metastudy. The DNA G+C content is 30.8%. Crassaminicella thermophila is likely to be transient and not a long-term gut coloniser. (Li2021b)



  • This organism has been recovered from a hydrothermal vent chimney. 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 50-55C, so unlikely to be a gut coloniser.
