Gram-negative rods, 0.8-0.9 x 1.6-2.3 μm.  Motile by means of lophotrichous flagella.
Non-spore-forming.
Colonies are cream-coloured, circular, convex with entire margins and 1-2 mm in
diameter after incubation on NA for 5 days at 30 ºC. No diffusible pigments are
produced. Good growth is observed on n
utrient agar and ISP 2 agar, with poor growth
on TSA and R2A agar. Growth occurs at 10-30 ºC (optimum, 30 ºC), at pH 7-8 and in
presence of
up to 2% (w/v) NaCl (optimum, 1%) in nutrient broth. Strictly aerobic.
Isolated from sap drawn from the Acer pictum Thunb. at Mount Halla in Jeju, Republic of Korea.
Undetermined.
