et al. 2007.
Gram-positive cocci, 0.8-1.2 μm, occuring singly, in pairs, tetrads or clumps. Non-
Colonies are circular, convex, yellow-pigmented and non-translucent with shiny,
glistening surfaces and entire margins, 2-3 mm in diameter after 3 days on Marine
Agar supplemented with 8 % (w/v) NaCl at pH 8.0 and 37 ºC. Also grows well on MA
supplemented with 2-15 % (w/v) MgCl2 or KCl instead of NaCl. Obligately aerobic.
Moderately halophilic; Growth occurs in media containing 0.5-25% NaCl; optimum 8-
10% NaCl. Grows at 4-45 ºC; optimal growth at 37 ºC. Grows in pH 6.0-10.0;
optimum pH 8.0.
Isolated from a brine sample collected from the Yipinglang salt mine in Kunming, China.
Susceptible to ampicillin (30 mg), chloramphenicol (30 μg), nalidixic acid (20 μg), novobiocin (30 μg), rifampicin (5 μg) and tetracycline
(30 μg). Resistant to gentamicin (10 μg), kanamycin (30 μg), lincomycin (2 μg), polymyxin B (30 μg) and streptomycin(10 μg).
