Overview

  • Sphingomonas glacialis 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 67.9%. Sphingomonas glacialis is likely to be transient and not a long-term gut coloniser. (Zhang2011)



  • This organism has been recovered from human faeces and glacier from Austria. Pathogenicity status unknown, or very unlikely to be pathogenic. Likely to be transient and not a long-term gut commensal.
    • QUIRKS
  • Can't grow at 37C, so unlikely to be a gut coloniser.
