Overview

  • Delftia lacustris 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 65.3%. Delftia lacustris is likely to be transient and not a long-term gut coloniser. (Jorgensen2009)



  • This organism has been recovered from mesotrophic lake water. Pathogenicity status unknown, or very unlikely to be pathogenic. Likely to be transient and not a long-term gut commensal.
    • QUIRKS
  • Borderline cold mesophile, so unlikely to be a gut coloniser.
