Gram-negative rods, 0.5-0.6 x 1.2-3.0 µm, in ZoBell 2216E broth. Non-motile,
nonflagellated, no endospores or capsules are formed.
Colonies on ZoBell 2216 agar are circular, smooth,  beige, convex. Luminescence is
not produced.
Grow on TCBS agar.
Facultatively anaerobic, mesophilic and neutrophilic chemo-organotroph
.
Can grow in nutrient broth with: 3% NaCl. No gowth in 0%, 1% or 6% NaCl. Growth
temperature 15 to 30 ºC. No growth at 4 or 37 ºC.
Isolated from the gut of French abalones (Haliotis tuberculata)  collected at the coastal area of Brest (Brittany, France).
Susceptible to O/129 vibriostatic agent.
Unknown. Could live in symbiosis with abalone.
