Bradyrhizobium elkanii

Description of Bradyrhizobium elkanii View in CoL Glm-3

(= KACC 10989)

Cells are Gram-negative, flagellated or non-flagellated, non-spore-forming rods (0.8 μm × 1.5 μm). Colonies are circular and white colored with less than 1 mm in diameter within 5 days at 28℃ on R2A medium. Catalase-negative and oxidase-positive. Positive for nitrate reduction and urease activity; but negative for indole production, glucose fermentation, arginine dihydrolase, aesculin hydrolysis, gelatin hydrolysis and β-galactosidase activity. According to API 20 NE test results, all assimilations were negative; D-glucose, L-arabinose, D-mannose, D-mannitol, N -acetylglucosamine, D-maltose, potassium gluconate, capric acid, adipic acid, malic acid, trisodium citrate and phenylacetic acid. It grow on YMA, R2A, NA, PDA media within 3 days at 28℃; but weakly grow on YPD, TSA, LB, Marine agar media within 5 days or more at 28℃ in the aerobic condition. Strain Glm-3 (= KACC 10989) was isolated from Glycine max sampled from Suwon-si, Gyeonggi-do. The GenBank accession number for the 16S rRNA gene and recA gene sequence of strain Glm-3 is PP986425 and PP990516, respectively.
