Gram-negative rods, 0.4 to 0.6 by 1.4 to 1.8 μm, occurring singly or in pairs. Motile by
polar flagella. Non-spore-forming.
polar flagella. Non-spore-forming.
Colonies on nutrient agar are circular, smooth or slightly rough, entire, raised,
glistening, pale yellowish brown, opalescent, butyrous. On nutrient agar slant:
moderate growth, filiform, glistening, pale brownish yellow. Fluorescence may be
present in early stages of isolation. Optimum temperature 25-30 ºC. No growth at 4 ºC
or 37 ºC. Aerobic. Able to grow in the presence of 3-5% NaCl. Growth media: Nutrient
Agar / Broth, Glutamate Agar / Broth, MacConkey agar.

P. nitroreducens was isolated from an oil brine in Japan. P. nitritireducens was solated from a wheat soil subjected to herbicides for
several years. P. multiresinivorans was isolated from a laboratory sequencing batch reactor in Canada.
