Gram-negative rods, 0.6-0.7 x 1.0-1.7 µm. Non-motile. Non-spore-forming.
Colonies grown on R2A agar for 3days are smooth, circular (1.0–1.5mm in diameter),
slightly viscous, non-transparent, yellow-pigmented, and concave with clear edges.
Grows on R2A agar at 20-33 ºC, at pH 4.0-8.0 and in the presence of 0-1.0% (w/v)
NaCl. Aerobic. Grows well on R2A agar, TSA and NA but not on LB or MacConkey agar.
