Overview

  • Micrococcus terreus is a Gram-positive, non-spore-forming, aerobic, non-motile, coccus bacterium. It has been detected in at least 1 gut microbiome compilation study or metastudy. The DNA G+C content is 67.2%. Micrococcus terreus is probably a rare gut coloniser. (Zhang2010)



  • This organism has been recovered from forest soil, China. Pathogenicity status unknown, or very unlikely to be pathogenic. A possible gut commensal.
