Phylum Proteobacteria, Class Betaproteobacteria, Order Burkholderiales, Family Alcaligenaceae, Genus Castellaniella,
Castellaniella ginsengisoli Kim et al. 2009.
Gram-negative rods, 0.7-0.8 x 1.6-2.5 μm. Non-spore-forming. Motile.
Colonies after 3 days incubation on R2A at 30 ºC, are 1-2 mm in diameter, smooth,
yellow coloured, circular and convex. Growth occurs on R2A agar, nutrient agar, TSA
and LB agar at 25-42 ºC, optimally at 30 ºC and at pH 5.0-9.0, optimally at pH 6.5-7.0.
Isolated from soil of a ginseng field in Daejeon, South Korea.
