Gram-negative, rods, 1.8-3.2 x 0.4-0.5 µm, motile by means of a single polar
flagellum.
flagellum.
Colonies on TS agar are nonluminescent, circular, not swarming, red-pink.
Can grow in nutrient broth with: 0.1 to 10% NaCl. No growth in 0% NaCl. Growth occur
at 20-42 ºC. No growth at 4 or 45 ºC. Optimum growth occurs at 25-30 ºC, pH 7 and in
2%NaCl. Facultatively anaerobic.
