Overview

  • Anoxybacillus flavithermus, (aka Bacillus flavothermus), is a Gram-positive, spore-forming, facultatively anaerobic, motile, rod-shaped bacterium. It has been detected in at least 2 gut microbiome compilation studies or metastudies. The DNA G+C content is 41.6%. Anoxybacillus flavithermus is unlikely to be a gut coloniser. (Pikuta2000; Heinen1982)



  • This organism has been recovered from a New Zealand hotsprings. 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
  • Weak growth at 37 degrees so unlikely to be a gut coloniser.
