Gram-negative rods, 0.6-0.7 x 1.3-1.9 µm. Motile by a monopolar flagellum. Non-
spore-forming.
spore-forming.
Colonies on Nutrient agar, after 1-2 days of incubation at 30 ºC, are 1-3 mm in
diameter, round to ovoid with irregular margins, flat and pale yellow. Growth occurs at
15-40 ºC (optimum, 30-37 ºC), at pH 6.0-8.0 (optimum, pH 7.0) and on R2A agar
supplemented with 0-5% NaCl (optimum, 1%).
