Gram negative, 0.6-0.8 x 1.2-1.8, motile by 1 to 3 polar flagellum, rods with rounded
ends.
Nonfluorescent, yellowish-brown colonies. Endospores are not formed. Granules of
poly-beta-hydroxybutyrate do not accumulate in the cells.
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.
Isolated from rice & other plants (cereals). One isolate from human cerebrospinal fluid.
One report of meningitis in humans caused by P. fulva.

Utilization of D-glucose, D-ribose, L-arabinose, 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 & ethanol = positive. Acid is produced from glucose.  Arginine
dihydrolase,  catalase & oxidase are positive.

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,
5-keto-D-gluconate, glucosamine, malonate, adipate, azelate, sebacate, citraconate, glycolate, hydroxybutyrate, tartrate,
DL-2-aminobutyrate, PHB, n-butanol, geraniol, phenol, benzoate, salicylate, m-hydroxybenzoate,  protocatechuate, gentisate,
mandelate, xylene, p-aminobenzoate, naphthalene, taurocholate, testosterone, D-aspartate, tryptophan, DL-norvaline, creatine,
anthranilate, hippurate, pantothenate, glutathione, acetamide, tryptamine, meso-erythritol & benzylamine are negative.
Acid is not produced from glycerol, xylose, sucrose, lactose & starch. Nitrates not reduced, H
2S is not produced, starch is not
hydrolyzed.

Utilization of isobutyrate, D-galactonolactone, isobutanol, 1-hexanol, benzylformate, phenyl acetate, L-threonine, L-phenylalanine,
L-tyrosine, L-histidine, amylamine & dodecane are variable.

P. fulva can be differentiated from P. parafulva by the assimilation of Tween 80, levulinate, itaconate, L-citrulline & nicotinate and  
non-assimilation of  p-hydroxy benzoate, butyrate & valerate.
