Colonies are circular, convex, smooth and pale yellow-colored after 2 days of incubation on R2 A at 30° C. Negative reactions are obtained for cytochrome oxidase, nitrate reduction, indole production, glucose fermentation, arginine dihydrolase, urease, esculin hydrolysis and gelatinase in API 20NE. Does not utilize L- arabinose, adipic acid, trisodium citrate and phenylacetic acid. Strain dN13-1 ( = NIBRBAC000502457) was isolated from a sludge sample, Suwon, Gyeonggi-do , Korea .
