Other AbstractOrganic pollutants including chemical pesticides, petroleum compounds, polycyclic aromatic hydrocarbons (PAHs) and polychlorinated biphenyls (PCBs), have caused serious environmental problems and posed new threats to human health when released into environments. Therefore, studies on the remediation of organic pollutants in contaminated-sites have received great concern. Plant-microorganism combined remediation of organic pollutants is a method to enrich, fix and degrade organic pollutants in soil by means of plant-microbe composite system, which is highly efficient, environmentally friendly and cheap, and has been paid more and more attention. On the one hand, the roots of plants continue to provide secretions and other metabolites for microorganisms, improve the contents of soil organic matter in roots, thus increasing the microbial diversity andl activity, and promoting the ability of microbial remediation of organic pollutants. On the other hand, rhizosphere microorganisms secrete organic acids and other substances, are able to change the existing state or redox state of organic pollutants in the environment, and reduce the toxicity of organic compounds to plants, strengthen the tolerance of plants, and promote the absorption, transfer and enrichment of organic pollutants. Plantmicroorganism is mutually beneficial to each other, which can enhance the effect of phytoremediation. The combined forms of phytoremediation include plant-rhizosphere microorganisms, plant-mycorrhizal fungi, plant-endophyte and plantspecific degrading bacteria. In recent years, a series of advances have been made in phytoremediation of plant-microorganism combination. Examples include that the interaction of alfalfa and soil microbe can greatly reduce the concentration of PCBs in soil, and the inoculation of rhizobium and mycorrhizal fungi enhances the ability of alfalfa to remove PCBs. Regarding the problems raised in the development of bioremediation, the following three aspects should be emphasized in the study of plant-microorganism remediation in the future: 1) Screen selected microbial strains and plant materials to improve the remediation efficiency of microbe and resistance of plants; 2) strengthen the real-time monitoring ability of bioremediation process of organic pollutants, optimize and control the living environment of plants and microorganisms, and improve the efficiency of remediation; 3) improve the degradation efficiency by enhancing the bioavailability of pollutants to strengthen the bioremediation effect.
