Overview

  • Microvirgula aerodenitrificans is a Gram-negative, non-spore-forming, aerobic, motile, rod-shaped - curved bacterium. It has been detected in at least 2 gut microbiome compilation studies or metastudies. The DNA G+C content is 65%. Microvirgula aerodenitrificans is likely to be transient and not a long-term gut coloniser. (Cleenwerck2003; Patureau1998; Patureau2005Bergey)



  • This organism has been recovered from human faeces (diarrhoea - CCUG), and activated sludge. 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.
