Abstract

The use of pesticides and the subsequent accumulation of residues in the soil has become a worldwide problem. Organochlorine (OC) pesticides have spread widely in the environment and caused contamination from past agricultural activities. This article reviews the bioremediation of pesticide compounds in soil using microbial enzymes, including the enzymatic degradation pathway and the recent development of enzyme-mediated bioremediation. Enzyme-mediated bioremediation is divided into phase I and phase II, where the former increases the solubility of pesticide compounds through oxidation-reduction and hydrolysis reactions, while the latter transforms toxic pollutants into less toxic or nontoxic products through conjugation reactions. The identified enzymes that can degrade OC insecticides include dehalogenases, phenol hydroxylase, and laccases. Recent developments to improve enzyme-mediated bioremediation include immobilization, encapsulation, and protein engineering, which ensure its stability, recyclability, handling and storage, and better control of the reaction.

微生物酶在分解受农药污染的土壤中的功能：综述。

农药的使用及其在土壤中的残留积累已成为一个世界性问题。有机氯（OC）杀虫剂在环境中广泛传播，并在过去的农业活动中造成污染。本文综述了利用微生物酶对土壤中的农药化合物进行生物修复的情况，包括酶降解途径和酶介导生物修复的最新发展。酶介导生物修复分为第一阶段和第二阶段，前者通过氧化还原和水解反应增加农药化合物的溶解度，后者通过共轭反应将有毒污染物转化为毒性较低或无毒的产物。已发现的可降解 OC 杀虫剂的酶包括脱卤酶、苯酚羟化酶和裂解酶。最近在改进酶介导的生物修复方面取得的进展包括固定化、封装和蛋白质工程，这确保了酶的稳定性、可回收性、处理和储存，以及对反应的更好控制。

期刊介绍： Bioprocess and Biosystems Engineering provides an international peer-reviewed forum to facilitate the discussion between engineering and biological science to find efficient solutions in the development and improvement of bioprocesses. The aim of the journal is to focus more attention on the multidisciplinary approaches for integrative bioprocess design. Of special interest are the rational manipulation of biosystems through metabolic engineering techniques to provide new biocatalysts as well as the model based design of bioprocesses (up-stream processing, bioreactor operation and downstream processing) that will lead to new and sustainable production processes. Contributions are targeted at new approaches for rational and evolutive design of cellular systems by taking into account the environment and constraints of technical production processes, integration of recombinant technology and process design, as well as new hybrid intersections such as bioinformatics and process systems engineering. Manuscripts concerning the design, simulation, experimental validation, control, and economic as well as ecological evaluation of novel processes using biosystems or parts thereof (e.g., enzymes, microorganisms, mammalian cells, plant cells, or tissue), their related products, or technical devices are also encouraged. The Editors will consider papers for publication based on novelty, their impact on biotechnological production and their contribution to the advancement of bioprocess and biosystems engineering science. Submission of papers dealing with routine aspects of bioprocess engineering (e.g., routine application of established methodologies, and description of established equipment) are discouraged.
