Overview

  • Shewanella decolorationis is a Gram-negative, non-spore-forming, facultatively anaerobic, motile, rod-shaped bacterium. It has been detected in at least 1 gut microbiome compilation study or metastudy. The DNA G+C content is 49.3%. Shewanella decolorationis is probably a rare gut coloniser. (Xu2005)



  • This organism has been recovered from activated sludge of a waste-water treatment plant, China. 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. A possible gut commensal.
