Gram-negative rods, 0.4-0.5 x 1.8-2.7 µm. Motile by one polar flagellum.
After cultivation for 48 h on R2A agar at 30 ºC, colonies are yellowish and 1-2 mm in
diameter.Colonies on King’s B agar produce fluorescent pigment. Grows at 15-37 ºC
(optimum 30 ºC), but not at 4 or 45 ºC, at pH 7.0-10.0 and in the presence of 1% (w/v)
NaCl. Strictly aerobic

Isolated from water from Baiyangdian Lake, China.
Resistant to rifamycin SV and vancomycin. Sensitive to minocycline and aztreonam.
