Overview

  • Micrococcus endophyticus is a Gram-positive, non-spore-forming, aerobic, non-motile, coccus bacterium. It has been detected in at least 3 gut microbiome compilation studies or metastudies. The DNA G+C content is 72.9%. Micrococcus endophyticus is likely to be transient and not a long-term gut coloniser. (Chen2009)



  • This organism has been recovered from human faeces and plant roots. 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.
