Gram-negative, slightly curved rods, 0.3-0.5 x 1.5-2.5 μm. Motile by a single polar flagellum. Non-spore-forming. Non-encapsulated.
Colonies on blood agar incubated in aerobic conditions at 30 ºC for 48 h are 2-4 mm
in diameter, beige to off-white, circular with entire margins, convex, and
non-swarming. Pigments are not produced. Grows on blood agar at room
temperature (18-22 ºC) and 30 ºC under both aerobic and microaerobic conditions.
Growth is slightly enhanced by adding 1% NaCl to media. No growth is observed
under
anaerobic conditions as well as under aerobic or microaerobic conditions at 37 ºC or
42 ºC. No haemolysis produced on TSA + 5% sheep blood. Under aerobic conditions
at 30 ºC grows on Marine Agar, minimal medium and on nutrient medium + 5%
sheep blood containing 0.5-4% (w/v) NaCl; 0.1% sodium deoxycholate; 0.05%
safranin; or 0.005% basic fuchsine. No growth occurs on, MacConkey agar, CCDA,
and on nutrient medium + 5% sheep blood containing 1% glycine, 0.01-0.1% TTC, 64
mg / l cefoperazone, 1% oxgall, 0.0005% crystal violet or 0.001% brilliant green.

Isolated from mussels collected at the Ebro river delta, Catalonia, Spain.
Undetermined.

Positive results for indoxyl acetate hydrolysis, oxidase and urease.
Negative results for amylase, catalase, casein hydrolysis, H2S production on TSI, lecithinase, nitrate reduction, and acid production
from glucose.
