Yang, Luo and Fang  2009.
Gram-positive, motile (peritrichous flagella) rods, 0.7-0.8 x 1.8-3.0 µm, producing
subterminal / paracentral, oval endospores  in usually swollen sporangia.
Colonies are brown, circular, with shiny, glistening and granular surfaces, 3-5 mm in
diameter after 1 day on BHI agar; on nutrient agar the colonies are smaller (1-3 mm in
diameter), pale and opaque. Aerobic.
Grow at pH 6-11  (optimum pH 7-8). Temperature range 7-45 ºC; optimum growth at
35-37 ºC. NaCl is not  required for growth; tolerates up to 8% NaCl. Optimum growth
occurs in nutrient broth with 0-2% NaCl added.
Isolated from a sand soil sample in Korla, China.
Susceptible to chloramphenicol, kanamycin, erythromycin, gentamicin, penicillin G, streptomycin, tetracycline and vancomycin.
Not determined.
