Overview

  • Robertmurraya andreesenii, (aka Bacillus andreesenii), is a Gram-positive, 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 39%. Robertmurraya andreesenii is likely to be transient and not a long-term gut coloniser. (Kosowski2014)



  • This organism has been recovered from a compost bioreactor. Pathogenicity status unknown, or very unlikely to be pathogenic. Likely to be transient and not a long-term gut commensal.
    • QUIRKS
  • Obligate aerobe; unlikely to be a gut coloniser.
