Gram-negative rods, 0.4-0.5 x 1.5-2 µm, non-spore-forming, motile by means of polar
flagella.
flagella.
After 72 h incubation at 15 °C on TSA, colonies are 1.5–2.0 mm in diameter, smooth
and round with irregular edges. Do not produce fluorescent pigment on King’s B
medium.
Aerobic, psychrotolerant. Growth occurs at temperatures between -4 and 30 °C, but
not at 37 °C. NaCl is tolerated at concentrations up to 4% (w/v).
