Description of Hymenobacter qilianensis 17Bio_15

Cells are Gram-stain-negative, non-flagellated, and long rod-shaped. Colonies are pink-colored after 3 days of incubation on R2A at 25°C. In the BIOLOG GEN III, α -D-glucose, D-arabitol, L-arginine, L-aspartic acid, Dgluconic acid, and citric acid are utilized as sole carbon source. But acetoacetic acid, N -acetyl-D-mannosamine, L-alanine, D-cellobiose, dextrin, D-fructose, D-fructose 6-PO 4, L-galactonic acid lactone, D-galactose, D-galacturonic acid, gelatin, gentiobiose, glucuronamide, D-glucuronic acid, L-glutamic acid, inosine, α -keto-glutaric acid, L-malic acid, D-maltose, D-mannitol, D-mannose, D-melibiose, β -methyl-D-glucoside, 3-methyl glucose, myo-inositol, pectin, propionic acid, glycyl-L-proline, Lpyroglutamic acid, quinic acid, D-raffinose, L-rhamnose, L-serine, stachyose, sucrose, D-trehalose, D-turanose, acetic acid, N -acetyl-D-galactosamine, N -acetyl-neuraminic acid, N -acetyl-D-glucosamine, γ -amino-butryric acid, D-aspartic acid, bromo-succinic acid, formic acid, D-fucose, L-fucose, D-glucose-6-PO 4, glycerol, L-histidine, α -hydroxybutyric acid, β -hydroxy-D, L-butyric acid, p -hydroxy-phenylacetic acid, α -keto-butyric acid, L-lactic acid, D-lactic acid methyl ester, α -D-lactose, D-malic acid, methyl pyruvate, mucic acid, D-saccharic acid, D-salicin, D-serine, D-sorbitol, and tween 40 are not utilized. In sensitivity tests, the tetrazolium redox dye is reduced in the presence of rifamycin SV, minocycline, lincomycin, and tetrazolium but not 1% NaCl, 1% sodium lactate, 4% NaCl, 8% NaCl, guanidine HCl, lithium chloride, pH 6, potassium tellurite, D-serine, sodium butyrate, tetrazolium violet, aztreonam, fusidic acid, nalidixic acid, niaproof 4, pH 5, sodium bromate, troleandomycin, and vancomycin.

Indole production is negative (API 20NE). In the API 20NE and ID 32GN systems, positive for reduction of nitrates (NO 3) to nitrogen (N 2), arginine dihydrolase, urease, esculin hydrolysis, β -galactosidase, D-saccharose (sucrose), itaconic acid, glycogen, 3-hydroxybenzoic acid, propionic acid, valeric acid, trisodium citrate, and potassium 2-ketogluconate. Weak for gelatin hydrolysis. Negative for reduction of nitrates (NO 3) to nitrite (NO 2 -), Indole production on tryptophan, glucose fermentation, D-glucose, L-arabinose, D-mannose, D-mannitol, Dmaltose, capric acid, adipic acid, malic acid, trisodium citrate, phenylacetic acid, L-rhamnose, N -acetyl-glucosamine, D-ribose, inositol, D-maltose, suberic acid, sodium malonate, sodium acetate, lactic acid, L-alanine, potassium 5-ketogluconate, L-serine, D-mannitol, D-glucose, salicin, D-melibiose, D-fucose, D-sorbitol, L-arabinose, L-histidine, 3-hydroxybutyric acid, 4-hydroxybrnzoic acid, and L-proline.

Strain 17Bio_15 (= NIBRBAC000500513) was isolated from a soil sample, Seoul, Nowon-gu Gongneung-dong, Korea.
