Gram-negative rods. Motile. Non-spore-forming.
Colonies are circular, white, translucent, raised and smooth after 24 h of incubation at
35 ºC on nutrient agar. Growth occurs at 4-40 ºC with optimal growth at 35-37 ºC, but
not at 42, 45 or 50 ºC. Grows at pH 5.0-10.0 (optimally at pH 6.0–7.0) and in the
presence of 0-8% (w/v) NaCl in tryptic soy broth. Facultatively anaerobic.
