Synonyms: Pseudomonas balearica Bennasar et al. 1996,
Pseudomonas stutzeri genomovar 6.
Gram-negative, short, straight, rods, 0.3-0.5 x 1.5 to 3.0 μm. Motile by means of a single
polar flagellum.
Colonies are not pigmented and very similar to P. stutzeri, forming characteristic
wrinkly dry colony morphology when isolates are fresh. Can grow up to 46°C and in
the presence of up to 8.5% NaCl. Strictly aerobic.
Isolated as 2-methylnaphthalene degraders at 40°C from wastewater and marine sediment samples.
Undetermined.

Can be differentiated from P. stutzeri by its ability to use xylose as a sole carbon and energy source and its inability to use mannitol,
galactose, ethylene glycol, 4-aminobutyrate, and suberate.
