Colonies are filamentous, raised, undulate and cream colored after incubation for 3 days on R2 A agar at 37℃. In the API 20NE system, positive reaction for nitrate reduction, glucose fermentation (weak), hydrolysis of esculin (weak) and gelatin, β-galactosidase activity and utilization of D-glucose, L-arabinose, D-mannose, D­mannitol, N ­acetyl­glucosamine, D­maltose, potassium gluconate, adipic acid (weak), malic acid and trisodium citrate. In the API 20NE system, negative reaction for indole production, arginine dihydrolase, urease activity and utilization of capric acid and phenylacetic acid. Strain R-5 ( = NIBRBAC000503388) was isolated from soil in Gurye , Jeollanam Province , Korea ( 35°11′16.0″N 127°33′ 02.5″E ).
