Colonies are smooth, convex and pink colored after incubation for 3 days on R2 A agar at 25℃. In the API 20NE system, positive reaction for indole production, urease activity, hydrolysis of gelatin and utilization of D-glucose, L-arabinose and D-mannose. In the API 20NE system, negative reaction for nitrate reduction, glucose fermentation, arginine dihydrolase, hydrolysis of esculin, β-galactosidase activity, oxidase activity and utilization of D-mannitol, N ­acetyl­glucosamine, D­maltose, potassium gluconate, capric acid, adipic acid, malic acid, trisodium citrate and phenylacetic acid. Strain R12 ( = NIBRBAC000503418) was isolated from ginseng­cultivated soil in Yeongju , Gyeongsangbuk Province , Korea ( 36°53′51.5″N 128°28′02.3″E ).
