Gram negative, 0.5 / 3-4 μm, motile rods with polar monotrichous flagellation.
Colourless to brownish-red colonies. No diffusible pigments produced.
Strictly aerobic, optimal temperature 25 -32 ºC, No growth at 41 ºC. Some strains
grow at 4 ºC. Organic growth factors not required.
Chemoorganotrophic, but may grow autotrophically in atmospheres with H2, CO2 & O2.

Can use more than 40 different carbon sources (sucrose, L-arabinose, trehalose,
raffinose, cellobiose, D-galactose, mannose, D-ribose, glucose, fructose, sucrose,
D-xylose, rhamnose, glutarate, acetate, pyruvate, butyrate, lactate, L-malate, citrate,
succinate, fumarate, L-proline, isobutanol).
Oxidase, catalase, gelatin & starch hydrolysis positive. Produce 2-keto-3-deoxy-6-
phosphogalactonate aldolase, 2-keto-3-deoxy-6-phosphogluconate aldolase,
D-galactose dehydrogenase, mannose isomerase, pullulanase, sucrose phosphorylase & alpha-amylase.
