Gram-negative, small rods, 0.5 to 0.9 by 1.0 to 1.9 µm, occuring singly. Motile by
peritrichous flagella. Non-spore-forming.
peritrichous flagella. Non-spore-forming.
Colonies on glucose-yeast extract agar are non-pigmented, opaque, milky white,
smooth, and low convex with entire margins. The optimal temperature is 30 to 46 ºC.
Facultatively anaerobic. Positive for growth on 0.5% KCN. Tolerates 35% glucose and
6% NaCl but not 40% glucose or 8% NaCl.

Positive results for arginine dihydrolase (after 4 days), catalase, citrate utilization, beta-galactosidase, malonate utilization, methyl red
test, phenylalanine deaminase, Voges-Proskauer test, acid production from L-arabinose, esculin, D-fructose, D-glucose, D-galactose,
maltose, D-mannitol, melibiose, L-rhamnose, L-sorbose, starch, sucrose, trehalose, and D-xylose. Lactose is fermented after 9 days
incubation.
Ammonium sulfate, yeast extract, urea, phenylalanine, glutamine, and tryptone are used as sole nitrogen sources.
Degrades 1 mol glucose to approximately 2 mol of ethanol and 2 mol of CO2 without hydrogen production.
Negative results for gelatinase, H2S production (on TSI), indole production, lysine decarboxylase, ornithin decarboxylase, oxidase,
urease, acid production from dulcitol, gluconate, myo-inositol, and raffinose.
