Gram-negative, slightly curved rods, 0.3-0.6 x 0.9-2.2 μm. Motile by a single polar flagellum. Non-encapsulated. Non-spore-forming.
Colonies on blood agar incubated under aerobic conditions at 30 ºC for 48-72 h are
1-3 mm in diameter, beige to off-white, circular with entire margins, convex, and
non-swarming. Pigments are not produced. The strain grows on blood agar at room
temperature (18-22 ºC), 30 ºC and 37 ºC but not at 42 ºC under microaerobic
conditions. Under aerobic conditions, it grows well at room temperature (18-22 ºC)
and 30 ºC but not at 37 ºC or 42 ºC. No growth is observed under anaerobic
conditions at 30 ºC. No haemolysis is observed on TSA medium supplemented with
5% sheep blood. Under aerobic conditions at 30 ºC the grows on minimal medium,
MacConkey agar, Marine agar or CCDA medium and on nutrient medium (0.5%, w/v
NaCl) supplemented with 5% sheep blood and also on this medium containing 2%
(w/v) NaCl. No growth occurs on nutrient medium supplemented with 5% sheep blood
containing 4% (w/v) NaCl, 1% glycine, 0.1% sodium deoxycholate, 1% oxgall, 0.01%,
0.04% or 0.1% 2,3,5 TTC; 0.001% brilliant green, 0.05% safranin, 0.0005% crystal
violet, 0.005% basic fuchsin and medium with 64 mg / l cefoperazone.
Isolated from a sample of clams from the locality of Ferrol, Galicia, Spain.
Undetermined.

Positive results for alkaline phosphatase, catalase, indoxyl acetate hydrolysis, nitrate reduction, oxidase, urease and
Voges-Proskauer test.
Negative results for casein hydrolysis, hippurate hydrolysis, H2S production on TSI, lecithinase and starch hydrolysis.
