Description of Flexivirga endophytica NSM-1

Cells are Gram-satin-positive and rod-shaped. Cell size is 2.5-2.7 μm. Colonies are circular, smooth, entire, and yellow pigmented after 3 days of incubation at 28°C on PTYG. Positive for reduction of urease, D-glucose, L-arabinose, D-mannose, gluconate, adipate, malate, and phenyl-acetate; but negative for nitrates to nitrite (NO 3 ->NO 2 -), reduction of nitrates to nitrogen, indole production, glucose acidification, arginine dihydrolase, β -gluco- sidase (esculin hydrolysis), protease (gelatin hydrolysis), β -Galactosidase (PNPG), D-mannitol, N -acetyl-D-glu- cosamine, D-maltose, caprate, and citrate. Utilizes D-glucose, L-fucose, L-arabinose, propionate, valerate, 2-ke- togluconate, 3-hydroxy-butyrate, L-rhamnose, D-ribose, itaconate, suberate, acetate, lactate, 5-ketogluconate, and 3-hydroxy-benzoate; but does not utilize D-mannitol, salicin, D-melibiose, D-sorbitol, caprate, citrate, L-histidine, 4-hydroxy-benzoate, L-proline, N -acetyl-D-glucosamine, inositol, D-sucrose, D-maltose, malonate, L-alanine, glycogen, and L-serine. Enzymatic activity reaction was positive for alkaline phosphatase, esterase (C4), esterase lipase (C8), leucine arylamidase, trypsin, acid phosphatase, and naphtol-AS-BI-phosphohydrolase; but negative for lipase (C14), valine arylamidase, cystine arylamidase, α -chymotrypsin, α -galactosidase, β -galactosidase, β -glu- curonidase, α -glucosidase, β -glucosidase, N -acetyl- β -glu- cosaminidase, α -mannosidase, and α -fucosidase. Strain NSM-1 (= NIBRBAC000509137) was isolated from an agricultural soil sample, Chungcheongnam-do, Korea.
