Gram-negative rods, 0.8-1.1 x 1.6-2.6 µm. Motile by 1-2 polar flagella.
Non-spore-forming.
Non-spore-forming.
Colonies on plate count agar are pale yellow to light cream in colour, opaque, round
with entire margins, raised, smooth, glistening and usually around 1-1.5 mm in
diameter after 2 daysincubation at 27 ºC. Growth occurs at 4-35 ºC, in the presence of
0-6% (w/v) NaCl and at pH 5-8. Positive for fluorescent pigment production on King’s
B medium. No diffusible pigments are produced when cultured on standard methods
agar plates. Aerobic.
