Overview

  • Bacillus mojavensis is a Gram-positive, spore-forming, aerobic, motile, rod-shaped bacterium. It has been detected in at least 2 gut microbiome compilation studies or metastudies. The DNA G+C content is 43%. Bacillus mojavensis is probably a rare gut coloniser. (Logan2011Bergey; Roberts1994)



  • This organism has been recovered from desert soils and human faeces. 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. Is a known gut commensal. Robust growth can have positive consequences for gut health.
