Gram-negative rods, 0.3-0.4 x 1.1-1.4 μm. Non-motile.
Colonies on R2A medium were opaque-white colored and irregular-raised in shape
(2.1-5.3 mm) after incubation for 2 days at 30 ºC. Growth range 20–35 ºC (optimum 30
ºC), pH 5.5-10.5 (optimum pH 7.0), and 0–0.6 % NaCl. Grows on Nutrient Agar (NA)
and R2A but not on TSA, MacConkey agar, or Blood agar. Facultative anaerobe.

glucosidase, leucine arylamidase, nitrate reduction to nitrite, oxidase, Tween 20 and 80 hydrolysis, valine arylamidase, cystine
arylamidase and naphtol-AS-BI-phosphohydrolase.
