Description of Pontibacter mucosus JN2214

Cells are Gram-stain-negative and rod-shaped. Cell size is 1.3-1.5 μm. Colonies are circular, smooth, entire, and pink pigmented after 7 days of incubation at 28°C on R2A. Positive for reduction of urease, β -glucosidase (esculin hydrolysis), protease (gelatin hydrolysis), D-glucose, L-arabinose, D-mannose, D-mannitol, and N -acetyl-D-glucosamine; but negative for nitrates to nitrite (NO - 3> NO 2 -), reduction of nitrates to nitrogen, indole production, glucose acidification, arginine dihydrolase, β -Galactosidase (PNPG), D-maltose, gluconate, caprate, adipate, malate, citrate, and phenyl-acetate. Utilizes D-mannitol, D-glucose, L-fucose, L-arabinose, L-rhamnose, and N -acetyl-D-glucosamine; but does not utilize salicin, D-melibiose, D-sorbitol, propionate, caprate, valerate, citrate, L-histidine, 2-ketogluconate, 3-hydroxy-bu- tyrate, 4-hydroxy-benzoate, L-proline, D-ribose, inositol, D-sucrose, D-maltose, itaconate, suberate, malonate, acetate, lactate, L-alanine, 5-ketogluconate, glycogen, 3-hydroxy-benzoate, and L-serine. Enzymatic activity reaction was positive for alkaline phosphatase, esterase (C4), esterase lipase (C8), leucine arylamidase, valine arylamidase, cystine arylamidase, acid phosphatase, naphtol-AS-BI-phosphohydrolase, α -galactosidase, α -gluco- sidase, β -glucosidase, and N -acetyl- β -glucosaminidase; but negative for lipase (C14), trypsin, α -chymotrypsin, β -galactosidase, β -glucuronidase, α -mannosidase, and α -fucosidase. Strain JN2214 (= NIBRBAC000509135) was isolated from an agricultural soil sample, Jeju Island, Korea.
