Gram-negative rods, 0.5-0.6 x 1.2-1.8 µm, occuring singly. Motile by one flagellum.
Colonies are faint yellow, circular, opaque, convex with entire margins, smooth and
approximately 0.5-1.0 mm in diameter after incubation for 2 days at 30 ºC on TSA
plates. Growth occurs at 4-41 ºC (optimally at 30 ºC), pH 4.0-11.0 (optimally at pH
6.0-8.0 and in 1-3% (w/v) NaCl media (optimally in 0-1% NaCl). Facultatively anaerobic.
