Overview


  • Methylobacterium phyllosphaerae is a Gram-negative, non-spore-forming, strictly aerobic, motile, rod-shaped bacterium. It has been detected in at least 1 gut microbiome compilation study or metastudy. The DNA G+C content is 66.8%. Methylobacterium phyllosphaerae is likely to be transient and not a long-term gut coloniser. (Madhaiyan2009)



  • This organism has been recovered from rice 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.
