Species description is based on a single isolate.
Gram-positive rods, 0.5-0.9 x 1.7-4.6 µm. Motile by flagella. Produce endospores.
Colonies are 0.5-1.5 mm in diameter, cream, circular and elevated on MA plates
after 2 days incubation. Growth occurs at 25-45 ºC (optimum 37 ºC), pH 6.5-9.0
(optimum 8.0) and NaCl 0-10% (v/v) (optimum 4%). Strictly aerobic.
Isolated from a salt mine in Kuche county, Xinjiang province, China.
Susceptible to amikacin, amoxicillin, cefoxitin, cefotaxime, chloramphenicol, ciprofloxacin, erythromycin, gentamicin, kanamycin,
neomycin, nitrofurantoin, norfloxacin, novobiocin, rifampicin, sulfamethoxazole,
tobramycin and vancomycin. Resistant to bacitracin, nystatin and polymyxin.
