Colonies are circular, smooth and light orange colored after incubation for 3 days on R2 A agar at 25℃. In the API 20NE system, positive reaction for nitrate reduction and utilization of D-glucose, D-mannose, D­mannitol, potassium gluconate, capric acid, malic acid, trisodium citrate and phenylacetic acid. In the API 20NE system, negative reaction for indole production, glucose fermentation, arginine dihydrolase, urease activity, hydrolysis of esculin and gelatin, β-galactosidase activity, oxidase activity and utilization of L-arabinose, N ­acetyl­glucosamine, D­maltose and adipic acid. Strain G37 ( = NIBRBAC000503413) was isolated from ginseng­cultivated soil in Yeongju , Gyeongsangbuk Province , Korea ( 36°53′51.5″N 128°28′02.3″E ).
