In API 20NE, urease, esculin hydrolysis, D-mannitol, potassium gluconate, malic acid and trisodium citrate were utilized;adipic acid were weakly utilized; whereas reduction 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, gelatin hydrolysis, β -galactosidase, D-glucose, L-arabinose, D-mannose, N -acetyl-D-glucosamine, D-maltose, capric acid and phenylacetic acid were not utilized. In the API 32GN test, glycogen and L-histidine were utilized; while L-rhamnose, N -acetyl-glucosamine, D-ribose, inositol, D-saccharose (sucrose), D-maltose, itaconic acid, suberic acid, sodium malonate, sodium acetate, lactic acid, L-alanine, potassium 5-ketogluconate, 3-hydroxybenzoic acid, L-serine, D-mannitol, D-glucose, salicin, D-melibiose, D-fucose, D-sorbitol, L-arabinose, propionic acid, capric acid, valeric acid, trisodium citrate, potassium 2-ketogluconate, 3-hydroxybutyric acid, 4-hydroxybenzoic acid and L-proline were not utilized. Strain BT 582 (= NIBRBA C000506218) was isolated from a soil sample from Guri-si, Gyeonggi-do, Korea .
