Phylum Firmicutes, Class Bacilli, Order Bacillales, Family Staphylococcaceae, Genus Aliicoccus, Aliicoccus persicus Amoozegar et al.
Gram-positive cocci, 0.7-0.8 μm diameter. Non-spore-forming. Non-motile.
Colonies are circular, entire, smooth and pale yellow, 1.6-1.8 mm in diameter on
7.5% HM agar medium after 48 h of incubation at 35 ºC. Moderately halophilic,
growing with 0.5-12.5% (w/v) NaCl, with optimal growth at 5-7.5 % (w/v) NaCl. No
growth in 0% NaCl. Grows at 20-45 ºC (optimally at 35 ºC) and pH 7.0-10.0 (optimally
at pH 8.0). Strictly aerobic.
Isolated from Aran-Bidgol hypersaline lake in Iran.
