Overview

  • Lacticigenium naphtae is a Gram-variable, non-spore-forming, facultatively anaerobic, motile, oval-shaped bacterium. It has been detected in at least 1 gut microbiome compilation study or metastudy. The DNA G+C content is 38%. Lacticigenium naphtae is unlikely to be a gut coloniser. (Iino2009)



  • This organism has been recovered from crude oil-water. Pathogenicity status unknown, or very unlikely to be pathogenic. Likely to be transient and not a long-term gut commensal.
    • QUIRKS
  • Likely not a gut coloniser since it doesn't grow at body temperature
