Old synonym:
Marinococcus hispanicus Marquez et al. 1990.
Gram-positive cocci, 1.0-2.0 μm, occuring singly, in pairs, tetrads or clumps. Non-
motile. Non-spore-forming.
Colonies on 10% salt complex medium are round and smooth and form a non-
diffusible, reddish orange pigment. Broth cultures are uniformly turbid. Strictly aerobic.
Hemolysis is produced. Growth occurs at pH 5.0
-9.0; optimum at pH 7.5. Moderately
halophilic; Growth occurs in media containing 0.5
-25% NaCl; optimum 10% NaCl.  
No growth occurs in the absence of NaCl. Grows at 15
-37 ºC; optimal growth at 37 ºC.
Isolated from soils and ponds of a solar saltern near Alicante, Spain.
Undetermined.
