Colonies are circular, raised, entire, and palecream colored after 3 days of incubation at 30℃ on R2A. Positive for nitrate reduction and esculin hydrolysis. Negative for indole production, glucose fermentation, and arginine dihydrolase, urease, gelatinase, and β -galactosidase activities. Does not utilize D- glucose, L- arabinose D- mannose, D- mannitol, N -acetylglucosamine, D- maltose, potassium gluconate, capric acid, adipic acid, malic acid, trisodium citrate, and phenylacetic acid. Strain MMS19-R33 ( = NIBRBAC000503369) was isolated from a soil sample, Gurye, Korea .
