Overview


  • Halobacillus salinus is a Gram-positive, 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 45%. Halobacillus salinus is probably a rare gut coloniser. (Yoon2003a)



  • This organism has been recovered from salt lake in Korea. 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. A possible gut commensal.

  • QUIRKS
  • Requires at least 2% salt concentration for optimal growth.
