Gram-negative rods, 0.2-0.4 x 0.4-10 μm. Non-flagellated.
Colonies on modified TSA are circular, raised to slightly convex, smooth, glistening,
deep greyish yellow in colour and 1.5-2.5 mm in diameter after incubation for 5 days
at 30 ºC. Optimal temperature for growth is 30 ºC; growth occurs at 4 and 30 ºC, but
not at 35 ºC. Optimal pH for growth is 7.0-8.0; growth occurs at pH 5.5, but not at pH
5.0. Growth occurs with 0-3.0% (w/v) NaCl (optimum, 0-0.5%). Growth occurs under
anaerobic conditions on modified TSA and on modified TSA supplemented with
nitrate. Facultative aerobic.

Susceptible to ampicillin, carbenicillin, cephalotin, chloramphenicol, gentamicin, kanamycin, lincomycin, neomycin, oleandomycin,
penicillin G, polymyxin B, streptomycin, and tetracycline. Resistant to novobiocin.
