Overview

  • Sphingomonas melonis 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 65.0%. Sphingomonas melonis is probably a rare gut coloniser. (Buonaurio2002)



  • This organism has been recovered from fruit disease, Japan. The risk classification (www.baua.de) for this organism is 1, i.e., low risk of infection and spread (notes: plant pathogen). Pathogenicity status unknown, or very unlikely to be pathogenic. A possible gut commensal.
