Association of Rhizobium sp. with two legumes on atrazine toleranceThe association of bacteria with plants has been studied as a possible emerging technology for phytoremediation of contaminants, including herbicides, which pose as a threatening to environmental quality due to their recalcitrance. The aim of this study was to assess the tolerance of dwarf mucuna (Stizolobium deeringianum Bort) and black mucuna (Stizolobium aterrimum Piper & Tracy) inoculated and uninoculated with Rhizobium to the herbicide atrazine. The treatments were: plants with inoculant + 0.1 g/m 2 , 0.2 g/m 2 atrazine, and without atrazine (T1, T2 and T3, respectively), plants without inoculant + 0.1 g/m 2 , 0.2 g/m 2 atrazine and without atrazine (T4, T5 and T6, respectively). The experiment was arranged in a completely randomized design, with three replications. Plants were grown in a
