Macian, Ludwig, Schleifer, Pujalte and Garay, 2001.
Gram-negative rods, 2-4 x 0.4-0.6 µm, motile by one polar flagellum.
Unpigmented colonies on marine agar, green on TCBS agar. On marine agar
produce a shallow pit on the medium (agarolytic). Can grow in nutrient broth with: 1 -
6% NaCl. No growth in 0% NaCl, 8% NaCl, 10% NaCl & 12% NaCl.
Can grow at pH 10. Optimal growth at 30 -35 ºC. No growth at 4 ºC or 40 ºC.
Facultative anaerobe. No luminescence produced.
Isolated from seawater at the Mediterranean coast of Valencia (Spain). Sensitive to vibriostatic agent O/129.
