Gram-positive cocci, 0.65–0.90 μm, occuring singly or in pairs, tetrads or clumps.
Colonies on GMH medium are circular, white, opaque and slightly convex, 1.4-2.8 mm
in diameter after cultivation at 37 ºC for 2 days. Growth occurs at pH 5.5-9.0; optimum
at pH 7.5. Moderately halophilic; growth occurs in media containing 0-24% NaCl;
optimum 8% NaCl. Grows at 8-43 ºC; optimal growth at 28 ºC.
Isolated from saline soil in Qinghai province, China.
