Gram-negative, small, curved rods, 0.2-0.9 x 1-3 μm. Rarely helical cells. Coccoid
forms develop in old cultures. Motile by means of a single polar flagellum. Not
swarming on moist media.

Colonies are 2-3 mm in diameter, circular, convex, and have a beige to off-white color
after 48 hours incubation. A brown, water-soluble pigment is produced from
tryptophan. No growth at 4 or 42 ºC. Optimum growth temperature 25-30 ºC.
Does not grow at 37 ºC under aerobic or microaerobic conditions. Grows on media
containing 0.05% sodium fluoride, 1-7% NaCl, 0.02% safranin, KMnO4 but not on
charcoal-based media, or media containing 0.04% triphenyltetrazolium chloride,
1.0-2.0% ox bile, or 1% glycine.

Isolated from the roots and root-associated sediments of Spartina alterniflora growing in saline marshes.
Undetermined. Nitrogen fixing bacteria.

Positive results for urease, catalase, nitrate reduction, oxidase, indoxyl acetate hydrolysis & H2S production on TSI.
Negative results for alkaline phosphatase, DN-ase & hippurate hydrolysis. No carbohydrates fermentation.
