聚乙烯(Polyethylene,PE)作为全世界使用量最多的塑料之一,因其耐磨性、高分子量和抗损坏特性而在自然环境中持久存在.PE的破裂形成微塑料(Microplastics,MPs),这些微塑料已大量积累并对生态系统构成威胁.目前,已有研究表明PE能够被部分降解,但在寻找能够完全降解PE的微生物或酶,以及构建更完整的PE生物降解途径方面仍需深入研究.本文通过综述PE的分类、回收技术、表征方法、以及降解PE的微生物和酶的种类,探讨了生物降解的途径及其影响因素,并对未来研究方向从理论和应用两方面提出了建议,为继续探索其降解机制提供理论依据.
Research Progress on Biodegradation of Polyethylene(PE)
Polyethylene(PE),as one of the most used plastics in the world,has widely existed in the natural environment because of its wear-resistant,high molecular weight and indestructible properties.PE would break down into microplastics(MPs)and accumulate in large quantities,and currently MPs has become an important pollutant that affects the ecosystem.Currently,many studies have been demonstrated that PE could be partially degraded,but further research is needed in screening of microorganisms or enzymes that could completely degrade PE and construct a complete biodegradation pathway for PE.Therefore,this paper summarizes the classification,recycle methods and characterization methods of PE,microorganisms and enzymes that degrade PE,biodegradation pathways and influencing factors,and proposes future research directions of PE biodegradation.These findings provide theoretical basis for the degradation mechanism of PE.
