Gram-negative rods, 0.6-0.7 x 0.9-1.2 μm. Motile by amphitrichous flagella. Non-
spore-forming.
spore-forming.
Colonies growing on MacConkey agar are circular, convex and smooth with
non-entire margins and usually an elevated centre. Growth occurs at 5-40 ºC
(optimum temperature range for growth is 28-37 ºC). The pH range for growth is
between 4 and 10. NaCl above the concentration of 5% inhibits the growth.
Facultatively anaerobic.

Phytobacter ursingii can be differentiated from Phytobacter diazotrophicus on its ability to ferment D-serine and utilize L-sorbose.
