%X The combined remediation effects of host plant (Astragalus sinicus L.) inoculated with rhizobium Rhizobium huakuii on PCBs contaminated soils was studied using pot experiments. The results showed that soil PCBs concentrations of single incubation of Rhizobium huakuii (R) and single planting Astragalus sinicus L. (P) decreased by 20.5% and 23.0%, respectively. Astragalus sinicus L. with incubation of Rhizobium huakuii had a clear role in PCBs removal in soils, PCBs concentration in polluted soils decreased by 53.1%, all of which were significantly higher than the untreated soils (P<0.01). We also observed that soil microbial communities in Astragalus sinicus L. rhizosphere soils had a higher microbial biomass C and N and carbon utilization rate, improving the functional diversity of the soil microbial community. The results suggested the great potential of planting Astragalus sinicus L. with incubation of Rhizobium huakuii in remediation of PCBs contaminated soils.
