Overview

  • Paenibacillus chitinolyticus, (aka Bacillus chitinolyticus), is a Gram-variable, spore-forming, aerobic, motile, rod-shaped bacterium. It has been detected in at least 1 gut microbiome compilation study or metastudy. The DNA G+C content is 51-53%. Paenibacillus chitinolyticus is probably a rare gut coloniser. (Lee2004; Kuroshima1996)



  • This organism has been recovered from human faeces, clinical samples (pleural fluid - CCUG) and forest soil from Japan. The risk classification (www.baua.de) for this organism is 1, i.e., low risk of infection and spread. Is a rare opportunistic pathogen. A possible gut commensal.
