Overview

  • Nitriliruptor alkaliphilus is a Gram-positive, non-spore-forming, strictly aerobic, non-motile, rod-shaped bacterium. It has been detected in at least 1 gut microbiome compilation study or metastudy. The DNA G+C content is 70.8%. Nitriliruptor alkaliphilus is likely to be transient and not a long-term gut coloniser. (Sorokin2009)



  • This organism has been recovered from soda lakes, Russia. Pathogenicity status unknown, or very unlikely to be pathogenic. Likely to be transient and not a long-term gut commensal.
    • QUIRKS
  • Obligate alkaliphilic, requiring at least pH 8 to grow; unlikely gut commensal. Utilises nitriles and amides for energy, C and N sources.
