Overview


  • Paracoccus sphaerophysae 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 67.1%. Paracoccus sphaerophysae is likely to be transient and not a long-term gut coloniser. (Deng2011)



  • This organism has been recovered from root nodules and human faeces. 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.
