Overview

  • Allobaculum mucilyticum is a Gram-positive, strictly anaerobic, non-motile, rod-shaped bacterium. The DNA G+C content is 48.6%. Allobaculum mucilyticum is probably a rare gut coloniser. (vanMuijlwijk2023)



  • This organism has been recovered from human faeces (UC patient). Could be a possible pathogen in humans, but unknown at this stage. A possible gut commensal. Robust growth can have unknown consequences for gut health.
