Yoshizawa et al. 2009.
Gram-negative, coccoid rods, motile by means of more than one polar flagellum.
Colonies on Marine agar are nonpigmented, translucent, nonswarming. Luminescent.
Colonies on TCBS agar are round, 2
-3 mm and green coloured. Growth occurs in  0.9-
3.5% NaCl (w/v) media, but not at 0.5, 6, 8 or 10% NaCl. Grows at 10-25 ºC, but not at
4, 30 or 37 ºC.
Isolated from seawater of Sagami bay in Japan.
