Gram-negative rods, 0.6 x 1.3-1.5 µm. Motile.
Colonies are milk-white, circular with entire margins, smooth and approximately 1-1.2
mm in diameter after incubation for 2 days at 30 ºC on TSA plates. Growth occurs at
4-41 ºC, optimally at 30 ºC. Able to grow at pH 4-10, optimally at pH 6.5, and in 1-6%
(w/v) NaCl. Facultatively anaerobic.
