et al. 2011.
Gram-positive cocci, 0.5-0.8 μm diameter. Non-motile. Non-spore-forming.
Colonies are circular, smooth, entire, slightly raised, pale yellow and 1-2 mm in
diameter after 3 days. A light pink, diffusible pigment is produced after a few days
incubation. Grows with 0.1-16% (w/v) NaCl (optimum 2-3% NaCl), at 4-40 ºC
(optimum 30-35 ºC) and at pH 5.5-10 (optimum pH 7.5). Facultatively anaerobic.
Isolated from salt lakes (2 strains), in China. Susceptible to rifampicin, ampicillin & gentamicin. Resistant to streptomycin,
chloramphenicol, kanamycin, erythromycin, tetracycline, spectinomycin & nalidixic acid.
