Overview

  • Azoarcus pumilus 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 66.5%. Azoarcus pumilus is probably a rare gut coloniser. (Fu2019)



  • This organism has been recovered from seawater in Sanya, China. Pathogenicity status unknown, or very unlikely to be pathogenic. A possible gut commensal.
