Overview

  • Thermomonas carbonis is a Gram-negative, non-spore-forming, aerobic, non-motile, rod-shaped bacterium. It has been detected in at least 1 gut microbiome compilation study or metastudy. The DNA G+C content is 67%. Thermomonas carbonis is likely to be transient and not a long-term gut coloniser. (Wang2014)



  • This organism has been recovered from human faeces and soil from a coal mine in China. Pathogenicity status unknown, or very unlikely to be pathogenic. Likely to be transient and not a long-term gut commensal.
    • QUIRKS
