Description of Novosphingobium mathurense EM 833

Cells are Gram-staining-negative, non-flagellated, and rod-shaped with 0.6-0.8 × 1.0-1.5 μm in size. Colonies are circular, smooth, entire and pale-yellow colored after three days of incubation at 30℃ on R2 A. The strain is positive for nitrate reduction, glucose fermentation, arginine dihydrolase, and β -galactosidase (esculin hydrolysis); but negative for indole production, and protease (gelatin hydrolysis). The strain assimilates D- glucose, L- arabinose, D- maltose, and citrate; but does not assimilate D- mannose, D- mannitol, N -acetyl-D- glucosamine, gluconate, caprate, adipate, malate, and phenylacetic acid. The strain utilizes D- glucose, salicin, D- melibiose, L- fucose, D- sorbitol, L- arabinose, propionate, caprate, valerate, citrate, L- histidine, 2-ketogluconate, 3-hydroxy-bu- tyrate, 4-hydroxy-benzoate, L- proline, L- rhamnose, N -acetyl-D- glucosamine, D- ribose, inositol, D- sucrose, and D- maltose; but does not utilize D- mannitol, D- melibiose, L- fucose, D- sorbitol, propionate, caprate, valerate, L- histi- dine, 2-ketogluconate, N -acetyl-D- glucosamine, D- ribose, inositol, itaconate, suberate, malonate, acetate, lactate, 5-ketogluconate, glycogen, 3-hydroxy-benzoate, and L- serine. The strain produces alkaline phosphatase, esterase (C4), esterase lipase (C8), leucine arylamidase, acid phosphatase, naphtol-AS-BI-phosphohydrolase, α -galac- tosidase, β -galactosidase, β -glucuronidase, α -glucosidase, and β -glucosidase; but does not produce lipase (C14), valine arylamidase, cystine arylamidase, trypsin, α -chymo- trypsin, N -acetyl- β -glucosaminidase, α -mannosidase, and α -fucosidase. Strain EM 833 (= NIBRBAC000506102) was isolated from a forest soil sample, Seoul, Korea .
