土壤农药残留物的微生物修复研究进展
Research Advances in Microbial Remediation of Soil Pesticide Residues
摘要
Abstract
Pesticide residues pose a major challenge to soil ecological security and agricultural product safety.Microbial degradation has emerged as a promising strategy for the remediation to farmland pollution due to its high efficiency and environmental compatibility,demonstrating broad application prospects.This review systematically elucidates the study and application advances in pesticide-degrading microorganisms,covering the following key aspects:In terms of degrading strain screening,various strategies—from traditional enrichment culture to microfluidic single-cell screening—have significantly enhanced both the efficiency and diversity of obtaining efficient degraders.Regarding degradation mechanisms,this review provides an in-depth analysis of key degradation gene functions,catalytic mechanisms of intracellular and extracellular enzymes,and synergistic enhancement of co-metabolic pathways.Concerning ecological processes,this review focuses on the colonization mechanisms of degrading bacteria in the rhizosphere and phyllosphere through chemotaxis and biofilm formation,along with their subsequent functional responses.It further examines both active migration mediated by flagellar motility and passive migration facilitated by environmental factors including hydraulic transport.In application technologies,this review examines the preparation processes of both liquid and solid formulations along with their respective advantages and limitations,and assesses the challenges in practical implementation,such as environmental adaptability,colonization efficiency,and ecological interactions.Finally,the review emphasizes that future efforts should focus on formulation innovations and plant-microbe interactions to enhance field stability and degradation efficacy of inoculants,thereby facilitating large-scale application of this technology and promoting agricultural green development.关键词
