Overview

  • Robertmurraya kyonggiensis, (aka Bacillus kyonggiensis), is a Gram-positive, spore-forming, facultatively anaerobic, 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 36.3%. Robertmurraya kyonggiensis is probably a rare gut coloniser. (Dong2011)



  • This organism has been recovered from soil from a lettuce field, Korea. Pathogenicity status unknown, or very unlikely to be pathogenic. A possible gut commensal.
