| rhizobium alvei sp. nov., isolated from a freshwater river. | a bacterial strain designated tnr-22(t) was isolated from a freshwater river in taiwan and characterized using a polyphasic taxonomic approach. cells of strain tnr-22(t) were facultatively anaerobic, gram-stain-negative, rod-shaped, motile by a single polar flagellum and formed cream-coloured colonies. growth occurred at 4-45 °c (optimum, 25-30 °c), with 0-1.0 % (w/v) nacl (optimum, 0.5 %) and at ph 7.0-8.0 (optimum, ph 7.0). strain tnr-22(t) did not form nodules on macroptilium atropurpureum. t ... | 2015 | 25385988 |
