Old synonym: Burkholderia grimmiae Tian et al. 2013.
Species description is based on a single isolate.
Gram-negative rods, 0.4-0.6 x 1.4-2.1 μm. Motile. Non-spore-forming.
Colonies are regular, circular, convex, translucent, moist and 1.0-3.0 mm in diameter
after 3 days of cultivation at 28 ºC on R2A. Grows on TSA, but not on MacConkey agar.
Temperature range for growth is 10-40 ºC (optimum 28-30 ºC) and pH 4.0-10.0
(optimum pH 7.0-7.5) in R2A broth. Growth occurs with 0-1% NaCl (optimal growth
without NaCl). Aerobic.
Isolated from the moss Grimmia montana, collected from Beijing Songshan National Nature Reserve, China.
