      Facultative anaerobic

      Colonies may produce a tan or buff pigment.

      It is common for pure cultures of vibrios to produce multiple colony morphologies (as many as 5), best seen on blood agar.

      Variations in morphology include smooth, rough, convex, flat spreading, and compact in various combinations.

      McConkey growth, non lactose fermenter

      TCBS yellow colonies
      (Yellow colonies may convert to green if plates are examined after more than 24 hours or are refrigerated after incubation.)

      BBAØ growth

      motility: can swarm on solid media by production of numerous lateral flagella
