Responses of Scirpus triqueter, soil enzymes and microbial community during phytoremediation of pyrene contaminated soil in simulated wetland

► Scirpus triqueter was used to eliminate pyrene. ► Scirpus triqueter enhanced the dissipation ratio of pyrene. ► Pyrene was a disadvantage for the growth of plant and the activity of soil enzyme. ► Microbial community structures were different at the presence of pyrene and plant. ► Rhizospheric soils had different microbial community from the control soils.
