Gram negative, 2-4 x 1-2 μm, motile.
Colonies are convex, round, beige , opaque, 1 cm in diameter (2 days / 28 °C, on
TSA), with entire and smooth margins; yellow colonies with raised margins on TCBS.
Grow on tryptone soy agar ( TSA) Oxoid supplemented with 2% NaCl and on
thiosulphate/citrate/bile salts/sucrose (TCBS) Difco. Is unable to grow in the absence
of Na+. Grow in marine broth with 2 - 6% NaCl.
Optimum growth temperature 20-30 °C, no growth is observed at 4 or 40 °C.
