Gram negative, 0.5 x 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 and O2 ..

Isolated from water and soil.
Unknown (none). Soil bacteria (nitrogen fixing bacteria).

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 and starch hydrolysis are positive. Produce 2-keto-3-deoxy-6-phosphogalactonate aldolase,
2-keto-3-deoxy-6-phosphogluconate aldolase, D-galactose dehydrogenase, mannose isomerase, pullulanase, sucrose
phosphorylase and alpha-amylase.
Negative results for arginine dihydrolase, 2-ketogluconate and nitrates reduction.
Cannot utilize glycerol, mannitol, sorbitol, ethanol, glycine, L-lysine, suberate, azelate and L-serine.
