Description of Cohnella rhizosphaerae 18JY42-3

Cells are Gram-stain-positive, aerobic and short rod-shaped. Colonies grown on R2A agar are circular, convex and beige after 3 days of incubation on R2A at 25℃.

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

In API 32GN system positive for L-rhamnose, D-maltose, suberic acid, sodium malonate, L-alanine, glycogen, 3-hydroxybenzoic acid, D-mannitol, D-glucose, salicin, D-melibiose, L-arabinose, propionic acid, capric acid, valeric acid, trisodium citrate, L-histidine, potassium 2-ketogluconate, 4-hydroxybenzoic acid, and L-proline. Negative for N -acetyl-glucosamine, D-ribose, inositol, D-saccharose (sucrose), itaconic acid, sodium acetate, lactic acid, potassium 5-ketogluconate, L-serine, D-fucose, D-sorbitol, and 3-hydroxybutyric acid. G + C mol for strain 18JY42-3 is 59.8%. Cells showed resistance to UV radiation. Strain 18JY42-3 (= NIBRBA0000116021) was isolated from a soil sample in Korea.
