Cerda-Cuellar, Rosselo - Mora, Lalucat, Jorfe and Blanch, 1997.
Gram-negative, motile, short rods. Nonspore-forming. No luminescence.
The optimal NaCl concentration for growth is 1 to 3% and it does not grow at higher
NaCl concentrations (6, 8, 10%) or below 0.5% NaCl. Growth temperature 22-35 °C,
no growth at  4 or 37 ºC.  
Halophilic, grows poorly in media containing under 0.5% NaCl. Facultatively anaerobe.
Colonies are unpigmented on TSA and yellow on TCBS agar (thiosulfate-citrate-bile
salts-sucrose agar).
Isolated from the intestines of juvenile turbot (Scophthalmus maximus) in a hatchery in Spain. Susceptible to vibriostatic agent 0/129.
Unknown.
