Gram-negative, rods, 0.75 x 2.1 µm. Motile. Non-spore-forming.
Colonies after incubation at 25 ºC for 24 h on TSG, are beige, smooth and round,
0.5-1.0 mm diameter. Growth occurs at 4-33 ºC (highest growth temperature varies
from 31 to 33 ºC; growth at temperatures lower than 4 ºC has not been tested).
Optimal growth temperature is between 23 and 27 ºC. Grows at pH 5-8 and in the
presence of up to 5% (w/v) NaCl. Grows on R2A agar and cetrimide agar. Fluorescent
on King B agar. No pyocyanin is formed on King A agar. Shows weak lipolysis on
tributyrin agar at 25 ºC after 10 days, but is negative for proteolysis using skimmed
milk agar at both 25 and 4 ºC. Haemolysis cannot be detected. No growth in
anaerobic conditions.
