Gram-negative rods, 2-4 x 8-40 μm. Non-motile. Non-spore-forming. Capsule is not

Colonies (48-72 h) on YCFA agar were very small, 0.5-1.5 mm in diameter, circular,
slightly convex, grey-white, glistening, and centrally opaque. Growth occurs at 25-45
ºC (optimum, 30-35 ºC) and in the presence of 0-3.5% (w/v) NaCl (optimum, 0.5-1.5
%). Strictly anaerobic, no growth in 5% CO2 air.
