Gram-negative rods, 0.3-0.4 x 1.2–3.2 µm, motile (non-flagellated). Non-spore-forming.
Colonies are light yellow, smooth, circular and convex with regular edges. When
tested on TSB, growth occurs within the temperature range of 15-42 ºC (not at 15 or
42 ºC), at pH from 6 to 9 and in 0-4% (w/v) NaCl. Aerobic.

Isolated from domestic sewage from Tianjin, China.
