Gram-negative, straight to slightly curved rods, 0.9 x 1.0-2.0 µm, motile.
Colonies on TSA with 1.5% NaCl are smooth, white, non-swarming, with
exo-polysaccharide production within 2 days at 28 ºC. No growth in TCBS. Facultative
anaerobe. Can grow in nutrient broth with: 1 to 5% NaCl (1-2% optimum). Growth
occurs at 20 to 37 ºC (28 ºC optimum). No growth at 4 or 45 ºC.
