摘要

新兴有机污染物(EOCs)污染土壤的全球挑战不断升级,需要先进的生物修复解决方案。本文综述了酶固定化和微生物工程在提高EOC降解方面的最新进展,重点介绍了纳米炭等创新载体系统及其在生物催化剂稳定中的作用。分析了EOCs与生物系统之间的关键分子相互作用,包括它们对DNA损伤和生态系统破坏的潜在影响,以及环境持久性带来的挑战。当代固定技术的关键比较基于细菌和酶系统中的相关基因评估其有效性,重点是结构和功能固定特性。此外,它强调了分子动力学模拟(MDS)的集成来预测EOC降解效率和酶-底物相互作用。革命性的基于crispr的基因工程方法用于定制微生物降解物,展示了它们在优化生物降解途径方面的精度。将固定化技术与工程微生物相结合的协同潜力,在计算建模和eoc降解预测模型的支持下,提供了一种比传统方法更有效地消除致病性化合物的生态友好解决方案。这种综合方法不仅具有成本效益,而且可以实现更快的污染物降解,与传统的修复策略相比,表现出优越的性能。这些技术既是当前技术的关键门槛,也是环境生物技术未来创新的路线图。

Bioremediation of soils with emerging organic contaminants using immobilized microorganisms
The escalating global challenge of soil contamination by emerging organic contaminants (EOCs) demands advanced bioremediation solutions. This review explores cutting-edge advancements in enzyme immobilization and microbial engineering for enhanced EOC degradation, focusing on innovative carrier systems like nanobiochar and their role in biocatalyst stabilization. Key molecular interactions between EOCs and biological systems are analyzed, including their potential for DNA damage and ecosystem disruption, alongside challenges posed by environmental persistence. A critical comparison of contemporary immobilization techniques evaluates their efficacy based on associated genes in bacterial and enzymatic systems, with emphasis on structural and functional immobilization characteristics. Furthermore, it highlights the integration of molecular dynamics simulations (MDS) to predict EOC degradation efficiency and enzyme-substrate interactions. Revolutionary CRISPR-based genetic engineering approaches for tailoring microbial degraders are demonstrated, showcasing their precision in optimizing biodegradation pathways. The synergistic potential of combining immobilization techniques with engineered microorganisms, supported by computational modeling and EOC-degradation predictive models, offers an eco-friendly solution that eliminates pathogenic compounds more efficiently than conventional methods. This integrated approach is not only cost-effective, but also achieves faster contaminant degradation, demonstrating superior performance compared to traditional remediation strategies. These techniques serve as both a critical threshold of current technologies and a roadmap for future innovations in environmental biotechnology.
