Elomari et al. 1997.
Gram-negative, nonsporogenous, motile rods.
Colonies on nutrient agar are circular and nonpigmented. They are nonhemolytic on
blood agar. A fluorescent pigment is produced. Poly-beta-hydroxybutyrate is not
accumulated as a carbon reserve material.
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.
Isolated from human clinical samples (placenta, stool, bile, biological fluid, bronchial aspirate, urine & pleural fluid).
Unknown, possible opportunistic pathogen.

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 & L-arginine arylamidase.
