Type species of the genus.
Gram-positive cocci, 1.0-2.5 μm in diameter, occuring singly, in pairs, tetrads or
clumps. Non-motile. Non-spore-forming.
Colonies  are  round,  smooth,  and  form  a  pink-red,  nondiffusible  pigment.  In  
liquid  medium  the  cultures  are  slightly turbid and form a viscous sediment. Strictly
aerobic. Moderately halophilic; growth occurs in media containing 0.9-25% NaCl;
optimum 10% NaCl.  Grows at 15-40 ºC; optimal growth at 37 ºC. Grows in pH
6.0-9.0; optimum pH 8.0.
Isolated from a marine saltern in Spain, salted meat, and salted horse hide.
Undetermined.
Positive results for catalase, casein hydrolysis, gelatin hydrolysis, nitrate reduction, oxidase & starch hydrolysis.
Can utilize as sole carbon and energy sources: D-gluconolactone, D-glucosamine, D-melibiose, sucrose, D-trehalose, erythritol,
ethanol, meso-inositol, propanol, D-sorbitol, N-acetylglucosamine,  aconitate,  alpha-aminobutyrate, benzoate, butyrate, citrate,
fumarate, DL-glycerate, D-gluconate, hippurate, DL-malate, propionate, quinate & D-tartrate.

Negative results for aesculin hydrolysis, arginine decarboxylase, Simmons’ citrate, H
2S  production, indole production, beta-
galactosidase, lysine decarboxylase, methyl red test, ornithine decarboxylase, phenylalanine deaminase, urease, Voges–Proskauer,
acid production from: arabinose, fructose, D-galactose, D-glucose, glycerol, lactose, maltose, D-mannitol, sucrose, D-trehalose & D-
xylose.
