Abstract

Purpose of Review

Neonicotinoids are synthetic insecticides, and among all agrochemicals, they rank second in consumption. The unparalleled use of neonicotinoids in various sectors including agriculture has currently reintroduced them as emerging pollutants/hazards due to their endocrine-disrupting nature. High water solubility, low volatility, and persistent nature have resulted in their accumulation in the environment. Thus, investigating efficient and sustainable methods for the remediation of contaminated environments due to this pollutant is imperative.

Recent Findings.

Bioremediation provides a cost-effective and environment-friendly option over conventional physicochemical techniques that produce toxic byproducts. The microbial route for degradation has the potential to completely mineralize neonicotinoids by virtue of their adaptive and diverse metabolic machinery. Potent microbes such as Ensifer, Phanerochaete, Bacillus, Ochrobactrum, Trametes, Rhodococcus, Sphingobacterium, and Pseudomonas have been isolated and screened for their immense degradation potential, and the metabolites, degradative enzymes, and transformation pathways have been elucidated. The incorporation of modern tools/techniques such as metabolic engineering, microbial biotechnology, omics-based database approaches or systems biology, artificial intelligence, and machine learning can fasten and give better bioremediation results.

Summary

This study has aimed to summarize the processes employed to date to degrade neonicotinoids and present a comprehensive report reflecting past efforts, advances, and future prospects. Therefore, this report will be beneficial in strengthening the understanding of the extent of efforts made for neonicotinoid degradation and how conventional approaches such as bioaugmentation, biostimulation, and biofiltration can be accelerated by advanced technologies viz., omics and machine learning.

新烟碱类生物降解:当前趋势和未来展望
综述目的新烟碱类杀虫剂是一种人工合成杀虫剂,在所有农用化学品中用量居第二位。新烟碱类在包括农业在内的各个部门的空前使用,由于其干扰内分泌的性质,目前已将其作为新出现的污染物/危害重新引入。高水溶性、低挥发性和持久性使其在环境中积累。因此,研究有效和可持续的方法来修复由于这种污染物而污染的环境是势在必行的。最近的发现。与产生有毒副产品的传统物理化学技术相比,生物修复提供了一种成本效益高、环境友好的选择。微生物降解途径凭借其适应性和多样化的代谢机制,具有完全矿化新烟碱的潜力。因其巨大的降解潜力,对Ensifer、Phanerochaete、Bacillus、Ochrobactrum、Trametes、Rhodococcus、Sphingobacterium和Pseudomonas等有效微生物进行了分离和筛选,并对其代谢产物、降解酶和转化途径进行了阐明。结合现代工具/技术,如代谢工程、微生物生物技术、基于组学的数据库方法或系统生物学、人工智能和机器学习,可以加快并提供更好的生物修复结果。本研究旨在总结迄今为止用于降解新烟碱类的工艺,并提出一份反映过去努力、进展和未来前景的综合报告。
