Phylum Proteobacteria, Class Gammaproteobacteria, Order Pseudomonadales, Family Pseudomonadaceae, Genus Pseudomonas,
Pseudomonas monteilii 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. 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.
