Gram-negative, 0.6-0.8 x 1.2-1.8, motile by 1 to 3 polar flagellum, rods with rounded
ends. Endospores are not formed. Granules of poly-beta-hydroxybutyrate are not
accumulated in the cells.

Nonfluorescent, yellowish-brown colonies. Strictly aerobic, optimal growth at 28 ºC,
can grow at 4 ºC, poor growth at 37 ºC, no growth at 41 ºC. Media: Nutritive agar,
Trypticase Soy Agar, King’s medium B agar, Pseudomonas agar P, Glutamate agar.

Positive results for arginine dihydrolase, catalase, oxidase and acid production from glucose.
Can utilize: glycerol, D-glucose, D-ribose, L-arabinose (one from two P. parafulva strains was negative), D-fructose, gluconate,
acetate, propionate, caprate, isovalerate, succinate, fumarate, itaconate, mucate, glycerate, L-lactate, D-malate, citrate, propylene
glycol, inosine, glycine, beta-alanine, L-valine, L-leucine, L-isoleucine, L-serine, L-lysine, L-ornithine, mannose and ethanol.
Negative results for beta-galactosidase, esculin hydrolysis, gelatin hydrolysis, nitrate reduction, H2S production and starch hydrolysis.
Acid is not produced from glycerol, xylose, sucrose, lactose and starch.
No utilization of: D-arabinose, D-xylose, D-galactose, L-rhamnose, L-fucose, sucrose, maltose, cellobiose, trehalose,
alpha-D-melibiose, lactose, raffinose, starch, inulin, adonitol, D-arabitol, L-arabitol, D-xylitol, sorbitol, mannitol, inositol,

anthranilate, hippurate, pantothenate, glutathione, acetamide, tryptamine, meso-erythritol and benzylamine.
Variable results for utilization of: isobutyrate, D-galactonolactone, isobutanol, 1-hexanol, benzylformate, phenyl acetate, L-threonine,
L-phenylalanine, L-tyrosine, L-histidine, amylamine and dodecane.
P. fulva can be differentiated from P. parafulva by urea hydrolysis, assimilation of L-arabinose, Tween 80, levulinate, itaconate,
L-citrulline or nicotinate and non-assimilation of phenylacetate, p-hydroxybenzoate, butyrate or valerate.
