Overview

  • Peribacillus psychrosaccharolyticus, (aka Bacillus psychrosaccharolyticus), is a Gram-variable, spore-forming, facultatively anaerobic, non-motile, pleiomorph rod-shaped bacterium. It has been detected in at least 1 gut microbiome compilation study or metastudy. The DNA G+C content is 43-44%. Peribacillus psychrosaccharolyticus is likely to be transient and not a long-term gut coloniser. (Patel2020; Priest1988; Logan2011Bergey)



  • This organism has been recovered from soil and lowland marshes. 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. A possible gut commensal.
    • QUIRKS
  • Unlikely gut coloniser because this organism doesn't grow at 37C.
