Overview

  • Psychrobacter maritimus is a Gram-negative, non-spore-forming, aerobic, non-motile, oval-shaped bacterium. It has been detected in at least 1 gut microbiome compilation study or metastudy. The DNA G+C content is 44.6-44.9%. Psychrobacter maritimus is likely to be transient and not a long-term gut coloniser. (Romanenko2004)



  • This organism has been recovered from human faeces and coastal sediment from Japan. The risk classification (www.baua.de) for this organism is 1, i.e., low risk of infection and spread. Pathogenicity status unknown, or very unlikely to be pathogenic. Likely to be transient and not a long-term gut commensal.
    • QUIRKS
  • Borderline cold mesophile, so unlikely to be a gut coloniser.
