Overview

  • Shewanella xiamenensis 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 46%. Shewanella xiamenensis is probably a rare gut coloniser. (Huang2010)



  • This organism has been recovered from coastal sediment, China. Pathogenicity status unknown, or very unlikely to be pathogenic. A possible gut commensal.
    • QUIRKS
  • Reduces Fe(III) to Fe(II) using lactate as an electron donor.
