Gram-negative rods, 0.5-0.8 x 1.0-2.5 μm. Non-motile. Non-spore-forming.
Colonies are yellow-pigmented, somewhat convex and non-translucent, with
glistening surfaces and circular / slightly irregular margins, and are 1-2 mm in
diameter after incubation for 3 days at 28 ºC on TSA. No diffusible pigments are
Growth occurs at 4-35 ºC (optimum, 25-30 ºC), in 0-5% (w/v) NaCl (optimum, 0.5-1%
(w/v) NaCl), and at pH 5.0-10.0 (optimum, pH 7.0). Facultatively anaerobic.
Isolated from a tidal flat sediment sample collected from the shore of Naozhou Island, Leizhou Bay, South China Sea, China.
