Overview

  • Hydrogenibacillus schlegelii, (aka Bacillus schlegelii), is a Gram-variable, spore-forming, strictly 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 62.3-65.4%. Hydrogenibacillus schlegelii is likely to be transient and not a long-term gut coloniser. (Kampfer2013; Logan2011Bergey)



  • This organism has been recovered from human faeces, lake, and soils. 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. Likely to be transient and not a long-term gut commensal.
    • QUIRKS
  • Produces spores, but is an obligate aerobe and doesn't grow at 37C. Unlikely to be a gut coloniser.
