Gram-negative rods, 0.5-0.7 x 1.5-2 μm. Motile. Non-spore-forming.
Colonies are light-beige, circular, 1-2 mm in diameter, translucent, with entire
margins, after 24 h incubation at 28 uC on nutrient agar. No specific pigment
(diffusible or fluorescent) is observed. The optimal growth temperature is 28 ºC.
Grows at 37 ºC but not at 42 ºC and in 1% NaCl, but not in 4% NaCl.
