Overview


  • Desulfovibrio diazotrophicus is a Gram-negative, non-spore-forming, strictly anaerobic, motile, rod-shaped - curved bacterium. The DNA G+C content is 62.1%. Desulfovibrio diazotrophicus is probably a rare gut coloniser. (Sayavedra2021)



  • This organism has been recovered from the human faeces (Sayavedra2021) of a healthy adult, China. Pathogenicity status unknown, or very unlikely to be pathogenic. A possible gut commensal.

  • QUIRKS
  • Able to respire sulfate using hydrogen, CO or alcohols. Can fix N2.
