Old synonym:
Vibrio calviensis  Denner, Vybiral, Fischer, Velimirov and Busse, 2002.
Gram-negative, straight or  slightly curved  rods,  0.25-1.0 x 0.75-2.5 μm, motile by one
polar flagellum.
Can grow in nutrient broth with: 1,5% to 12% NaCl (2.5-3.5% NaCl optimum). No
growth in 0% or 1% NaCl. Optimum growth temperature 30 ºC. Slow growth (10 days)
at 4 ºC. No growth at 37 ºC.
Facultatively anaerobic. No bioluminescence produced.
Grows on Bacto marine agar 2216 (Difco),
Sea-water agar, producing  brownish,
translucent, circular, smooth and convex colonies.
Grows on TCBS agar, producing green colonies.
Bacterium was isolated from sea water (Bay of Calvi, Corsica, France) by 0.2 μm membrane filtration.
Susceptible to vibriostatic agent O/129. Resistant to Lincomycin, Oxacillin and Spectinomycin.
Unknown.
