Colonies are pink colored after 3 days of incubation on R 2A at 25°C. In the BIOLOG GEN III test, weak positive for dextrin, D-trehalose, D-turanose, 1% NaCl, D-mannose, D-fructose, D-galactose, L-rhamnose, 1% sodium lactate, D-mannitol, D-arabitol, tetrazolium violet, methyl pyruvate, D-lactic acid methyl ester, citric acid, L-malic acid, bromo-succinic acid, nalidixic acid, potassium tellurite, α -hydroxy-butyric acid, β -hydroxy-D, L-butyric acid, α -keto-butyric acid, acetic acid, aztreonam and sodium bromate are positive. D-fructose-6- PO , glucuronamide, and acetoacetic acid. In the API 20NE test, positive for urease, D-mannitol, and N -acetyl-D-glucosamin; weak positive for esculin hydrolysis, D-glucose, L-arabinose, D-mannose, D-maltose, and potassium gluconate; but negative for gelatin hydrolysis, β -galactosidase, malic acid, trisodium citratereduction of nitrates (NO 3 ) to nitrite (NO 2 - ), reduction of nitrates (NO 3 ) to nitrogen (N 2 ), indole production on tryptophan, glucose fermentation, arginine dihydrolase, capric acid, adipic acid, and phenylacetic acid. In the API 32GN test, positive for D-saccharose (sucrose), D-maltose, sodium acetate, 3-hydroxybenzoic acid, D-mannitol, D-glucose, D-melibiose, L-arabinose, valeric acid, trisodium citrate, inositol, itaconic acid, sodium malonate, lactic acid, L-alanine, potassium 5-ketogluconate, L-serine, D-sorbitol, capric acid, L-histidine, potassium 2-ketogluconate, 3-hydroxybutyric acid, 4-hydroxybenzoic acid, and L-proline; but negative for L-rhamnose, salicin, N -acetyl-glucosamine, D-ribose, suberic acid, glycogen, D-fucose, and propionic acid. Strain BT115 (= NIBRBAC000502698) was isolated from a soil sample, Okcheon-gun, Chungcheongbuk-do , Korea .
