Overview

  • Bradyrhizobium ganzhouense is a Gram-negative, non-spore-forming, aerobic, non-motile, rod-shaped bacterium. It has been detected in at least 1 gut microbiome compilation study or metastudy. The DNA G+C content is 64.6%. Bradyrhizobium ganzhouense is likely to be transient and not a long-term gut coloniser. (Lu2014)



  • This organism has been recovered from the nodules of an Acacia sp. Pathogenicity status unknown, or very unlikely to be pathogenic. Likely to be transient and not a long-term gut commensal.
    • QUIRKS
  • Reported to not 'grow' on glucose, but apparently utilises it as a sole carbon source. Borderline cold mesophile, with optimum growth temp of 28C. Unlikely gut coloniser.
