Gram-negative rods, 0.6–0.8 x 2.2–4.2 μm, capsular with a flagellum and motile by
gliding.
gliding.
Colonies on nutrient agar are shiny, green and circular with regular, smooth edges
and are 1-2 mm in diameter after incubation for 48 h at 37 ºC. Grows at pH 4-10
(optimum 7-9) and at temperature 15-39 ºC (optimum 37 ºC). NaCl is not required for
growth but can tolerate NaCl concentrations up to 1% (w/v). Aerobe. Flexirubin-type
pigments are not produced. Produce a green pigment.

Description is based mostly on API 50CH, API 20E, API 20NE, and API ZYM results.
Positive results for acid and alkaline phosphatase, acetoin production, chitin hydrolysis, beta-glucosidase (esculin hydrolysis), gelatin
hydrolysis (API 20 NE, API 20 E), esterase (C4) (weak), lipase (C14) (weak), leucine aminopeptidase, alpha-chymotrypsin, trypsin,
naphthol-AS-Bl-phosphoamidase, valine arylamidase, acid production from aesculin-ferric-citrate, maltose, starch, glycogen,
potassium 5-ketogluconate, arabinose, glucose, mannitol, inositol, sorbitol, rhamnose, melibiose, sucrose and amygdalin.
Can assimilate D-glucose and maltose.
Negative results for arginine dihydrolase, casein hydrolysis, cystine arylamidase, esterase lipase (C8), alpha-fucosidase,
beta-galactosidase, beta-glucuronidase, alpha-glucosidase, N-acetyl-beta-glucosaminidase, gelatin hydrolysis (positive in API 20 NE
and 20 E), H2S production, indole production, lysine decarboxylase, alpha-mannosidase, ornithine decarboxylase, starch hydrolysis,
tryptophan deaminase and urea hydrolysis.
No assimilation of L-arabinose, D-mannose, D-mannitol, N-acetylglucosamine, potassium gluconate, capric acid, adipic acid, malic
acid, trisodium citrate and phenylacetic acid.
