Gram-negative curved rods, 0.3-0.5 x 0.4-1.1 μm. Non-motile.
Colonies grown on NSY agar are non-pigmented, circular and convex with smooth
surface. Growth occurs up to 38 ºC but not at 5 ºC. Growth occurs in 0-0.5 %
(w/v) NaCl. Aerobic; weak anaerobic.

Species can be discriminated from the type strain of P. cosmopolitanus by its ability to
assimilate malonic acid, and by growth at 38 ºC and lack of growth at 5 ºC.
Can assimilate acetate, propionate, pyruvate, malate, malonate, fumarate, succinate, oxaloacetate, L-alanine and L-cysteine. Weak
assimilation of D-galactose and D-galacturonic acid.
No assimilation of glycolate, glyoxylate, oxalate, citrate, levulinate, D-fructose, D-fucose, D-glucose, D-lyxose, D-mannose, D-sorbitol,
L-aspartate, Lasparagine, L-glutamate, L-serine or betaine.
