Overview

  • Deinococcus aquaticus is a Gram-negative, non-spore-forming, strictly aerobic, non-motile, rod-shaped bacterium. It has been detected in at least 2 gut microbiome compilation studies or metastudies. The DNA G+C content is 68.3%. Deinococcus aquaticus is likely to be transient and not a long-term gut coloniser. (Im2008)



  • This organism has been recovered from freshwater and human faeces. Pathogenicity status unknown, or very unlikely to be pathogenic. Likely to be transient and not a long-term gut commensal.
