Description of Methylobacterium populi 18JY76-11

Cells are Gram-stain-negative, aerobic, and short rod-shaped. Colonies are pink-colored and circular after 3 (1) (2) (3) days of incubation on R2A at 25℃.

In API 20NE system, positive for the reduction of nitrates (NO 3) to nitrite (NO 2 -), urease, D-glucose, L-arabinose, D-mannose, D-mannitol, N -acetyl-D-glucosamine, D-maltose, potassium gluconate, adipic acid, malic acid, and trisodium citrate. Negative for the reduction of nitrates (NO 3) to nitrogen (N 2), indole production on tryptophan, glucose fermentation, arginine dihydrolase, esculin hydrolysis, gelatin hydrolysis, β-galactosidase, and capric acid. Weak positive for assimilation of phenylacetic acid.

In API 32GN system, posiive for L-rhamnose, N -acetyl-glucosamine, D-ribose, inositol, D-saccharose (sucrose), D-maltose, suberic acid, sodium malonate, sodium acetate, lactic acid, L-alanine, potassium 5-ketogluconate, glycogen, 3-hydroxybenzoic acid, L-serine, D-mannitol, D-glucose, salicin, D-melibiose, D-fucose, D-sorbitol, L-arabinose, propionic acid, valeric acid, trisodium citrate, L-histidine, potassium 2-ketogluconate, 3-hydroxybutyric acid and L-proline. Negative for capric acid and 4-hydroxybenzoic acid. G + C mol for strain 18JY76-11 is 70.4%. Cells showed resistance to UV radiation. Strain 18JY76-11 (= NIBRBA0000116030) was isolated from a soil sample in Korea.
