| burkholderia symbiotica sp. nov., isolated from root nodules of mimosa spp. native to north east brazil. | four strains, jpy345t, jpy347, jpy366 and jpy581 were isolated from nitrogen-fixing nodules on the roots of two mimosa spp. (m. cordistipula, m. misera) native to north east brazil, and their taxonomic positions were investigated by a polyphasic approach. all four strains grew at 15-43 °c (optimum, 35 °c), at ph 4.0-7.0 (optimum, ph 5.0) and with 0-2 % nacl (optimum, 0 %). on the basis of 16s rrna gene sequence analysis, a representative strain (jpy345t) showed 97.3 % sequence similarity to t ... | 2011 | 22081715 |
