Gram negative, 0.5–0.90.7–2.1 µm, rods. Non-sporeforming. No flagella. Numerous
blebs occur on the cell surface.
Can grow in nutrient broth with:  3, 4, 6 &10% NaCl.  No growt in 0% NaCl. Growth
temperature 2 - 35 °C, no growth at  40 °C.  Non-pigmented colonies.
Isolated from a drainage pool at a fish processing plant where hydrogen peroxide was used as a bleaching agent.
Susceptible to vibriostatic compound O/129 (10 and 150 µg).
Unknown.
