昆虫降解塑料的机制及其研究方法

The mechanism and research methods of insect degradation of plastics

从昆虫降解塑料这一关键点出发,综述有关昆虫种类、取食降解塑料机制及其研究方法。发现国内外共有14种昆虫可取食塑料,其中某些昆虫对塑料的降解是其肠道微生物的作用,目前对昆虫降解塑料的研究方法包括产物分析法、稳定同位素示踪法、细菌培养法和宏基因组学法。展望该领域存在的问题及今后的研究方向,旨在为进一步利用昆虫降解环境污染物提供依据。

Starting from the key point of insect degradation plastics,this paper focuses on the review of insect species and the mechanism of eating degradation plastics.It is found that there are 14 types of insects eating plastic in the world,and the degradation of plastics by some insects is due to their intestinal microorganisms.At present,the research methods of insect degradation plastics include product analysis,stable isotope tracing,bacterial culture and metagenomics.Some problems in this field and future research directions are put forward.It is hoped that this paper can provide an overview of insects based strategies on degradation of environmental plastic pollution.
