Overview


  • Rubrobacter xylanophilus is a Gram-positive, non-spore-forming, aerobic, non-motile, pleiomorph rod-shaped bacterium. It has been detected in at least 1 gut microbiome compilation study or metastudy. The DNA G+C content is 67.6%. Rubrobacter xylanophilus is unlikely to be a gut coloniser. (Carreto1996)



  • This organism has been recovered from thermally polluted industrial runoff. The risk classification (www.baua.de) for this organism is 1, i.e., low risk of infection and spread. Pathogenicity status unknown, or very unlikely to be pathogenic. Non-colonising.

  • QUIRKS
  • Hydrolyses xylan. High optimum growth temperature suggests it is not a regular gut commensal
