Overview

  • Paenibacillus riograndensis is a Gram-variable, spore-forming, facultatively anaerobic, motile, rod-shaped bacterium. It has been detected in at least 1 gut microbiome compilation study or metastudy. The DNA G+C content is 55.1%. Paenibacillus riograndensis is likely to be transient and not a long-term gut coloniser. (Beneduzi2010)



  • This organism has been recovered from a plant rhizosphere, Brazil. Pathogenicity status unknown, or very unlikely to be pathogenic. Likely to be transient and not a long-term gut commensal.
    • QUIRKS
  • Borderline cold mesophile, with optimum growth temp of 28C. Unlikely gut coloniser.
