Phylum Firmicutes, Class Bacilli, Order Bacillales, Family Staphylococcaceae, Genus Salinicoccus, Salinicoccus hispanicus
(Marquez et al. 1990) Ventosa et al. 1993.
Old synonym: Marinococcus hispanicus Marquez et al. 1990.
Gram-positive cocci, 1.0-2.0 μm, occuring singly, in pairs, tetrads or clumps. Non-
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.
