Gram-negative rods, 0.55-0.65 x 1.5-2.8 µm. Non-spore-forming.
Colonies are fluorescent, white-yellowish, circular, 4mm in diameter, convex with
regular margins on King's B medium after 48h. Grows well on KB, LB, nutrient agar
and tryptic soya agar. Can grow at 5-41 ºC (weak), optimum 37 ºC, at pH 5-6 and in
1-8% NaCl. Aerobic.
