Colonies are circular, convex, smooth and yellow colored after 4 days on R2 A at 25° C. Nitrate is reduced and esculin is hydrolyzed. The strain shows positive reactions for enzyme activities of urease, gelatinase, arginine dihydrolase, and β -galactosidase. Indole is not produced and glucose is not fermented. The strain utilizes D-glucose, D-mannose, and D-maltose, whereas the strain does not utilize L-arabinose, D-mannitol, N -acetyl-glucosamine, potassium gluconate, adipic acid, capric acid, malic acid, trisodium citrate, and phenylacetic acid. Strain 17J28-11 (= NIBRBAC000501339) was isolated from a soil sample, Jeju , Korea .
