Overview

  • Aeribacillus pallidus, (aka Bacillus pallidus), 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 39-41%. Aeribacillus pallidus is likely to be transient and not a long-term gut coloniser. (MinanaGalbis2010; Muhammad2015; Banat2004)



  • This organism has been recovered from human faeces and heat-treated sewage sludge. Pathogenicity status unknown, or very unlikely to be pathogenic. Likely to be transient and not a long-term gut commensal.
    • QUIRKS
  • High optimum growth temperature so unlikely to be a gut coloniser.
