Overview


  • Alkalihalobacillus gibsonii, (aka Bacillus gibsonii), is a Gram-positive, spore-forming, aerobic, short rod-shaped bacterium. It has been detected in at least 1 gut microbiome compilation study or metastudy. The DNA G+C content is 41.1%. Alkalihalobacillus gibsonii is probably a rare gut coloniser. (Nielsen1995)



  • This organism has been recovered from soil. 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.
