Gram-negative, curved rods, motile by a single sheathed polar flagellum. Not
swarming on complex media. Bioluminescent, but this property is lost after storage
and subculture. Cells accumulate PHB.
Can grow in nutrient broth with: 1% NaCl, 6% NaCl & 8% NaCl. No growth in 0%
NaCl,10% NaCl & 12% NaCl. Growth temperature  4-35 ºC. No growth at 40 ºC.
Isolated from seawater and shrimp from the Yellow Sea, China.
Unknown.
