Gram-negative, motile with polar multitrichous flagella, sometimes twisted into a
fascicle or bundle, in a 24 hours culture; 0.5-1 x 3.0-9.0 µm.
fascicle or bundle, in a 24 hours culture; 0.5-1 x 3.0-9.0 µm.
Colonies are white, convex, round, translucent, waved on the edge and 3.0-6.0 mm in
diameter after 72 hours incubation on nutrient agar plates. Does not produce
fluorescent pigments. Aerobic, growth occurs at 15-42 ºC; no growth at 4 or 45 ºC.
Grows on medium containing 0-6.5% (w/v) NaCl. Grows on MacConkey agar.
