Overview

  • Paenibacillus naphthalenovorans is a Gram-positive, spore-forming, strictly aerobic, 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%. Paenibacillus naphthalenovorans is likely to be transient and not a long-term gut coloniser. (Priest2011Bergey; Daane2002)



  • This organism has been recovered from estuarine sediments and salt marsh rhizosphere. 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. Likely to be transient and not a long-term gut commensal.
    • QUIRKS
  • Can utilise naphthalene as a sole carbon source. Obligate aerobe; unlikely to be a gut coloniser.
