      abstract     = {Though phytoremediation is deemed as a promising approach
                      to restore polycyclic aromatic hydrocarbon (PAHs)
                      contaminated sites, studies about how the biodegradation of
                      PAHs is enhanced still remains incomprehensive. Effects of
                      root components on pyrene bioaccessibility, soil enzymes and
                      microbial communities were explored in the paper, and their
                      interactions in simulated pyrene and pyrene-diesel spiked
                      microcosms were tried to give a reasonable explanation.
                      Results indicated that root components enhanced the pyrene
                      removal of bioaccessible and adsorbed fractions by 16.10 and
                      1.80 mg kg− 1, respectively, in pyrene-spiked soils at the
                      end of the experiment. By contrast, root components
                      increased the degradation of bioaccessible fraction by only
                      3.3 mg kg− 1 in pyrene-diesel spiked soils. Although the
                      bound fractions of pyrene increased over time in treatments
                      without root components, they remained relatively stable,
                      ranging from 0.02 to 0.03 mg kg− 1, in root components
                      amended treatments. Activities of soil enzymes (polyphenol
                      oxidase, catalase, invertase, urease and alkaline
                      phosphatase) varied differently in response to pollutants
                      and root components. Analysis of phospholipid fatty acids
                      revealed that root components increased the biomass of soil
                      microorganisms and altered the microbial structure. Pearson
                      correlation analysis proved positive correlations between
                      all the microbial subgroups and pyrene removal in
                      pyrene-spiked soils, but the degradation of bioaccessible
                      pyrene was only positively related with microorganisms
                      confirmed by monounsaturated fatty acids in pyrene-diesel
                      spiked soils.},
