Gram-negative curved rods, 0.3-0.5 x 0.5-1.4 μm. Non-motile.
Colonies grown on NSY agar are unpigmented, circular and convex with smooth
surfaces and reach a diameter of 1 mm after 5-10 days at 20-24 ºC. Growth occurs at
10-35 ºC. Tolerate up to 0.3-0.5% (w/v) NaCl. Aerobic, some strains can grow
anaerobically.

Isolated from the water column (pelagic zone) of Lake Mondsee located in the Salzkammergut Lake District in Austria.

Species can be discriminated from the type strain of P. victoriensis by its inability to
assimilate malonic acid, and by growth at 5 ºC and lack of growth at 38 ºC.
Positive por catalase and oxidase.
Can assimilate acetate, pyruvate, propionate, oxaloacetate, malate, succinate, fumarate, D-galacturonic acid, D-galactose, L-cysteine
and L-alanine.
No assimilation of formate, glycolate, oxalate, D-lyxose, D-fructose, D-fucose, D-sorbitol, L-aspartate, L-serine, L-asparagine or
betaine.
