Gram-negative, curved rods, 1.8 - 2.4 x 0.7-0.8 µm, motile by means of a single polar,
sheathed flagellum (in liquid media).
Colonies on agar media (peptone/yeast extract glucose agar Difco) are red, circular &
not swarming. Nonluminescent. The red pigment is prodigiosin.

at 20-40 ºC (optimum 25-30 ºC. No growth at 4 or 45 ºC. pH 7.0 optimum.
Facultatively anaerobic. Mesophilic.
Isolated from a sea-water sample collected in the shallow coastal region of Keelung, Taiwan.
Resistant to the vibriostatic agent O/129.
Resistant to Cephalothin, Clindamycin, Lincomycin, Oxacillin & Vancomycin.
