摘要:

在长期的协同进化过程中,共生菌与昆虫宿主形成了较为稳定的共生关系。共生菌分布于昆虫体内外的多个部位,参与调节宿主昆虫的多种生理过程。一些昆虫共生菌能产生水解酶、氧化还原酶和转移酶,这些酶在降解聚烯烃类塑料、聚酯类塑料以及农药中发挥了关键作用,在环境生物修复中有一定的应用潜力。但是,由于塑料结构复杂且化学性质相对稳定,降解环境复杂多变,在环境生物修复中应用昆虫共生菌时需克服诸多难题,如共生菌及其产生的酶存在活性低、稳定性差、底物谱窄、安全性不明、降解产物存在毒性和破坏原生态平衡。本文对昆虫共生菌降解塑料和农药的机制、能降解塑料和农药的昆虫共生菌的种类、筛选方法及其在环境生物修复中的应用现状进行了综述,分析了存在的问题及其解决途径,并对未来的研究方向进行了展望,期望能为相关领域的研究提供参考和借鉴,推进昆虫共生菌在环境生物修复中的应用。

Abstract:

Symbiotic bacteria have developed close associations with their insect hosts during the long history of coevolution. They are distributed in multiple parts of insects, both inside and outside their bodies, and participate in the regulation of various physiological processes of insect hosts. Some insect symbiotic bacteria produce hydrolases, oxidoreductases, and transferases to degrade polyolefin plastics, polyester plastics and pesticides, and have certain application potential in environmental bioremediation. However, due to the complex structure and relatively stable chemical properties of plastics, complex and changeable degradation environment, many issues have to be overcome before popularization of insect symbiotic bacteria in environmental bioremediation, such as low activity, poor stability, narrow substrate spectrum, unknown safety, toxicity of degraded products of symbiotic bacteria and their enzymes, and their destruction on original ecological balance. This paper reviewed the mechanisms and strains of insect symbiotic bacteria degrading plastic and pesticide, methods of screening them, and application status in environmental bioremediation. This paper also analyzed the existing issues and the solutions to them and prospected the research directions. By this review, it is aimed to provide references and insights for studies in related fields and advance the application of insect symbiotic bacteria in environmental bioremediation.
