Erythrobacter aurantius

Description of Erythrobacter aurantius R31

The cells are Gram-stain-negative, non-flagellated, and rod-shaped. The colonies are circular, convex, entire, and yellow-colored after incubating for 7 days on MA at 30℃. They are positive for esculin hydrolysis, gelatin hydrolysis, and cytochrome oxidase; but negative for nitrate reduction, indole production, glucose fermentation, arginine dihydrolase, urease, and β -galactosidase in API 20NE. D- glucose, L- arabinose, D- mannose, D- mannitol, N -acetyl-glucosamine, D- maltose, potassium gluconate, capric acid, adipic acid, malic acid, trisodium citrate, and phenylacetic acid are not utilized as sole carbon sources. Strain R31 (= HNIBRBA7140) was isolated from a sea water sample from Seonjaedo Island (37°14 ʹ 12.1 ʺ N, 126°31 ʹ 24.6 ʺ E), Incheon, Korea. The GenBank accession number of the 16S rRNA gene sequence is PP079952 GoogleMaps .
