Overview

  • Alkaliphilus metalliredigens is a Gram-positive, spore-forming, strictly anaerobic, motile, rod-shaped bacterium. It has been detected in at least 1 gut microbiome compilation study or metastudy. Alkaliphilus metalliredigens is probably a rare gut coloniser. (Ye2004)



  • This organism has been recovered from borate-enriched leachate ponds, USA. Pathogenicity status unknown, or very unlikely to be pathogenic. A possible gut commensal.
    • QUIRKS
  • Can grow in the presence of 10mM sodium borate. Yeast can be used as an electron donor and Fe(III), Co(III) or Cr(VI) as electron acceptors.
