Gram-negative rods, 0.6-1.1 x 1.2-3.0 µm. Motile by peritrichous flagella.
Colonies on LB agar supplemented with 10% sucrose are circular, smooth and
yellow-orange after 48 h of incubation at 28 ºC. Facultatively anaerobic. Growth occurs
at 4-35 ºC, optimally at 28-30 ºC; does not grow at 37 ºC. Grows in the presence of up
to 5% NaCl (optimally 3%) and up to 60% sucrose (optimally with 10–25% sucrose).
Poor growth in the absence of sucrose. Grows on MacConkey agar, Columbia blood
agar and BHI agar. Not haemolytic.
