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 H
2, CO2 & O2.
Isolated from water & soil.
Unknown (none). Soil bacteria (nitrogen fixing bacteria).
