Overview

  • Herbinix luporum is a Gram-positive, non-spore-forming, strictly anaerobic, 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 35.1%. Herbinix luporum is likely to be transient and not a long-term gut coloniser. (Koeck2016a)



  • This organism has been recovered from a thermophilic biogas plant, Germany. Pathogenicity status unknown, or very unlikely to be pathogenic. Likely to be transient and not a long-term gut commensal.
    • QUIRKS
  • High minimum growth temperature (40C) so unlikely to be a gut coloniser.
