Yumoto et al. 2001.
Gram-negative straight rods 0.3-0.5 x 1.5-3.0 μm, nonspore-forming, motile by means
of a single polar flagellum.
Colonies are circular and colourless. Growth occurs in media supplemented with
3.5%NaCl, but not in media with salinity higher than 9% at pH 10. Growth occurs at 4 -
30 ºC, but no growth is observed at 40 ºC or higher.
Isolated from seawater, Hokkaido, Japan.
Unknown.
