Overview

  • Psychrobacter fulvigenes is a Gram-negative, non-spore-forming, aerobic, non-motile, oval-shaped bacterium. Psychrobacter fulvigenes is probably a rare gut coloniser.



  • This organism has been recovered from marine crustaceans, Sea of Japan. Pathogenicity status unknown, or very unlikely to be pathogenic. A possible gut commensal.
