Synonym:
Pseudomonas pseudoalcaligenes  Stanier 1966.
According to Saha et al. 2010,
Pseudomonas pseudoalcaligenes Stanier 1966 is a
later heterotypic synonym of  
Pseudomonas oleovorans Lee and Chandler 1941.
Gram-negative, 0.5-0.8 / 1.2-2.5 µm, motile rods. When grown on agar, the cells are
almost coccoid, but the length increases during the exponential phase in broth.
Colonies have a typical fluorescence that is not imparted to the medium. Strictly
aerobic, optimal temperature 35 ºC, poor growth at 41 ºC. Grows on nutrient agar /
nutrient broth.
Isolated from soil, water & clinical samples (sputum, urine, sinus discharge,
cerebrospinal fluid) - rarely.
Pseudomonas oleovorans is isolated from oil-water
emulsions used as lubricants and cooling agents in the cutting and grinding of
metals. Apparently the organism lives on some normal constituent of the cutting
compound, probably the naphthenic acids, which act as emulsifying agents.
Opportunistic pathogen.
Possible cause of  meningitis or pneumonia (doubtful – admin note).
