Only one strain tested (the type strain, GMD509T ).
Gram-negative rods, 0.5-0.8 x 1-4 μm, motile by means of a polar flagellum.
Colonies are smooth, cream-coloured, opaque, convex. Grow on marine 2216E agar
Difco supplemented with 1% tributyrin. Is unable to grow in the absence of Na+. Grow
in the presence of 1-5% NaCl (3% NaCl optimally).
