Overview

  • Ruminiclostridium herbifermentans is a Gram-variable, spore-forming, anaerobic, motile, rod-shaped - curved bacterium. It has been detected in at least 1 gut microbiome compilation study or metastudy. The DNA G+C content is 33.2%. Ruminiclostridium herbifermentans is likely to be transient and not a long-term gut coloniser. (Rettenmaier2021)



  • This organism has been recovered from a lab-scale biogas fermenter fed with maize silage. Pathogenicity status unknown, or very unlikely to be pathogenic. Likely to be transient and not a long-term gut commensal.
