Description of Sphingomonas psychrotolerans DG 1-23

The cells are Gram-stain-negative, non-flagellated, and rod-shaped. The colonies are circular, slightly convex, glistening, and yellow-colored after incubating for 7 days on R2 A at 25℃. They are positive for nitrate reduction, indole production, esculin hydrolysis, gelatin hydrolysis, β -galactosidase, and cytochrome oxidase; but negative for glucose fermentation, arginine dihydrolase, and urease in API 20NE. D- glucose, L- arabinose, D- mannose, D- mannitol, N -acetyl-glucosamine, potassium gluconate, adipic acid, malic acid, trisodium citrate, and phenylacetic acid are utilized as sole carbon sources; but D- maltose and capric acid are not. Strain DG1-23 (= HNIBRBA7033) was isolated from a soil sample from Yeongheungdo Island (37°16 ʹ 51.2 ʺ N, 126°28 ʹ 28.51 ʺ E), Incheon, Korea. The GenBank accession number of the 16S rRNA gene sequence is OR342727 .
