Description of Flavobacterium circumlabens IMCC 33702

Cells are Gram-stain-negative, aerobic, non-flagellated, and rod-shaped. Colonies are irregular, convex, undulate, and yellow-colored after incubation for 3 days on R2A at 20℃. Positive for arginine dihydrolase, urease, esculin hydrolysis, and β-galactosidase; but negative for nitrate reduction, indole production, glucose fermentation, gelatin hydrolysis, and cytochrome oxidase 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 weakly utilized as sole carbon sources. Strain IMCC33702 (= NNIBR2020642BA2) was isolated from a freshwater sample, Chungju Lake, Chungju, Chungcheongbuk-do, Korea.
