Gram-negative, nonsporogenous, motile rods. Poly-beta-hydroxybutyrate is not
accumulated as a carbon reserve material.
accumulated as a carbon reserve material.
Colonies on nutrient agar are circular and nonpigmented. They are nonhemolytic on
blood agar. A fluorescent pigment is usualy produced.
Strictly aerobic, optimal growth temperature 30 ºC. Growth occurs in the presence of
3% NaCl but not in the presence of 5 or 7% NaCl. No growth at 4 ºC or 41ºC. Grows
on media: Trypticase Soy Agar ± 5% sheep blood, King medium A & B.

P. monteilii is very similar to P. putida, but these two species can be differentiated by assimilation of inositol, L-tartrate, D-tartrate,
o-hydroxybenzoate, m-hydroxybenzoate, tryptamine, D-mandelate, acetamide, D-xylose, mannitol & mucate and by the presence
of glycyl-glycine arylamidase, L-glutamine arylamidase, and L-arginine arylamidase.
Positive results for arginine dihyrolase, catalase and cytochrome oxidase.
