植物-微生物联合对环境有机污染物降解的研究进展

环境中有机污染物的过量积累对生态系统及人类健康造成严重威胁。近年来,许多学者研究发现植物-微生物联合作用对环境中有机污染物的去除及生态系统的修复具有非常显著的效果。本文主要从植物-内生菌、植物-菌根菌以及植物-根际微生物这三个层面详细阐述植物-微生物联合降解有机污染物的研究现状,分析植物-微生物在联合降解中的作用,揭示植物-微生物联合降解的机理。但就目前而言,植物-微生物联合降解有机污染物仍存在许多问题,植物-微生物联合降解有机污染物的机理及生态学效应仍不清楚。因此,还需要进一步探讨其潜在作用机制并加强应用实践,这将有助于污染生态系统的治理,促进环境可持续发展。

Progress in the degradation of environmental organic pollutants by plant-microorganism combination

The excessive accumulation of organic pollutants in the environment forms great threat to ecosystem and human health. In recent years, many researches have constantly showed prominent effects of the plant-microorganism combination on the degradation of environmental organic pollutants. It has been widely accepted that the plant-microorganism combination generally exists inside the plant and in the rhizosphere, which provides precondition to degrading the organic pollutants and lays foundation for practical application of environmental remediation. In this review, we summarized the research progress based on three aspects of the plant-microorganism combination, including plant-endophyte, plant-mycorrhiza and plant-rhizospheric microorganism. We analyzed the function of the plant-microorganism combination during the process of organic pollutants biodegradation and discussed the degradation mechanisms. However, there are still challenges to the study of the plant-microorganism combination degradation of environmental organic pollutants, the underlying mechanisms and ecological effects are unclear yet. Therefore, every effort should be made to further clarify the degradation mechanisms, as well as to enhance practical application, thus contributing to the ecosystem management and sustainable development.
