Gram-negative rods, 0.7-0.9 x 1.1-1.7 μm. Motile.
Colonies on R2A agar are white, round, convex, smooth and with entire margins
(1.5-2 mm in diameter after 6 days at 20 ºC). Pigment is not produced. Good growth
occurs in R2A liquid medium at 5-30 ºC (highest cell yields at 10-20 ºC); growth at 1
and 37 ºC is absent in R2A liquid culture and on R2A agar plates. On R2A agar,
growth occurs at pH 7-8 and with 0-7% (w/v) NaCl; growth is delayed with 10% (w/v)
NaCl and absent with 15% (w/v) NaCl.
