Overview

  • Bacillus wiedmannii 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 35.3%. Bacillus wiedmannii is probably a rare gut coloniser. (Miller2016)



  • This organism has been recovered from raw milk. Could be a possible pathogen in humans, but unknown at this stage. A possible gut commensal.
