| Pseudomonas laurentiana |
Positive results for acid phosphatase and catalase.
Can assimilate caprate, citrate, malate, phenylacetate, formic acid, D-serine, D-glucose, D-fructose, sucrose, lactose, yeast extract,
tryptone, formate, peptone, casamino acids, gamma-hydroxybutyric acid, tartaric acid, succinamic acid and phenylacetic acid.
Negative results for alkaline phosphatase, arginine dihydrolase, cystine arylamidase, aesculin hydrolysis, gelatin hydrolysis, indole
production, nitrate reduction, oxidase, PNPG, urease and acid production from glucose.
No utilization of adipate, mannitol, N-acetylglucosamine, maltose, mucic acid, L-phenylalanine, D-saccharic acid, Tween 40, inosine,
myo-inositol, ascorbate, xanthine, succinic acid, maleic acid, L-asparagine, L-methionine and L-phenylalanine.
Variable results for utilization of L-arabinose, gluconate and mannose.

Gram-negative, curved-rods, 0.5-0.7 x 1.75-2.2 µm. Motile by lophotrichous flagella.
Fluorescent pigment production on King’s B medium is not produced.
The optimum temperature for growth is 30 ºC; growth occurs at 10-30ºC but not at 4
ºC or 37 ºC. The optimal pH for growth is 7-7.5; growth occurs between pH 5.0-10.0.
Growth is observed in the presence of 0-3% NaCl (but not in ≥ 4 %) with an
optimal concentration of 0.5%. Aerobic.
