Description of Marmoricola aurantiacus low10-4-1

Cells are Gram-stain-negative and short rod-shaped. Colonies are yellow-colored after 3 days of incubation on R2A at 25°C. In the BIOLOG GEN III, D-trehalose, D-cellobiose, gentiobiose, sucrose, stachyose, Draffinose, D-galactose, inosine, D-sorbitol, glycerol, Dserine, L-alanine, L-arginine, L-aspartic acid, L-serine, D-gluconic acid, D-glucuronic acid, glucuronamide, and propionic acid are utilized as sole carbon source. But acetoacetic acid, N -acetyl-D-mannosamine, dextrin, D-fructose, D-fructose 6-PO 4, L-galactonic acid lactone, D-galacturonic acid, gelatin, α -D-glucose, L-glutamic acid, α -keto-glutaric acid, L-malic acid, D-maltose, Dmannitol, D-mannose, D-melibiose, β -methyl-D-glucoside, 3-methyl glucose, myo-inositol, pectin, glycyl-L-proline, L-pyroglutamic acid, quinic acid, L-rhamnose, D-turanose acetic acid, N -acetyl-D-galactosamine, N - acetyl-neuraminic acid, N -acetyl-D-glucosamine, γ - amino-butryric acid, D-arabitol, D-aspartic acid, bromo-succinic acid, citric acid, formic acid, D-fucose, L-fucose, D-glucose-6-PO 4, 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, and tween 40 are not utilized. In sensitivity tests, the tetrazolium redox dye is reduced in the presence of potassium tellurite and aztreonam, but not 1% NaCl, 1% sodium lactate, 4% NaCl, 8% NaCl, guanidine HCl, lithium chloride, pH 6, D-serine, sodium butyrate, tetrazolium violet fusidic acid, lincomycin, minocycline, nalidixic acid, niaproof 4, pH 5, rifamycin SV, sodium bromate, tetrazolium blue, 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, gelatin hydrolysis, β -galactosidase, D-ribose, D-saccharose (sucrose), D-maltose, suberic acid, sodium malonate, sodium acetate, lactic acid, L-alanine, glycogen, L-serine, D-mannitol, D-Glucose, salicin, L-arabinose, propionic acid, valeric acid, L-histidine, potassium 2-ketogluconate, 3-hydroxybutyric acid, 4-hydroxybenzoic acid, and L-proline. Negative for reduction of nitrates (NO 3) to nitrite (NO 2 -), glucose fermentation, N -acetyl-D-glucosamine, capric acid, adipic acid, trisodiumcitrate, phenylacetic acid, L-rhamnose, N -acetyl-glucosamine, inositol, itaconic acid, potassium 5-ketogluconate, 3-hydroxybenzoic acid, D-melibiose, D-fucose, D-sorbitol, capric acid, and trisodium citrate.

Strain low10-4-1 (= NIBRBAC000500523) was isolated from a soil sample, Seoul, Nowon-gu, Gongneung-dong, Korea.
