Species description is based on a single isolate.
Gram-negative, straight rods, 0.7 x 1.9-2.5 µm, occurring singly or in pairs. Motile by
single or multiple polar flagella. Non-sporogenous.
single or multiple polar flagella. Non-sporogenous.
Colonies are beige, circular convex, smooth, 0.5-1.0mm in diameter, after incubation
at 25 °C for 24h on Standard-I agar or Caso agar plus glucose, with brownish
colouring in areas of heavy confluent growth. Fluorescent on King B agar. A black
diffusible pigment and levan are produced on Czapek yeast extract agar. Growth
occurs at 2-33 ºC, optimally at 27-31 ºC. Growth occurs at pH 5.5-8.5 (optimum, pH
6.0-7.0) and in the presence of up to 6% (w/v) NaCl. Non-haemolytic. Strictly aerobic.
