Gram-negative rods, 0.4-0.6×1.3-2.2 µm. Motile by peritrichous flagella.
Colonies on LB agar are circular, smooth, yellow and 1–2mm in diameter within 48h
at 30 ºC. Growth occurs at 12-41 ºC (optimum, 20-40 ºC), at pH 4.5-9.0 (pH 6.0-7.5)
and in the presence of 0-7.5% (w/v) NaCl (1.0-1.5%). Facultatively anaerobic.
