Biological catalysts are emerging with the capability to depolymerize a wide variety of plastics. Improving and discovering these catalysts has leveraged a range of tools, including microbial ecology studies, high-throughput selections, and computationally guided mutational studies. In this review, we discuss the prospects for biological solutions to plastic recycling and upcycling with a focus on major advances in polyethylene terephthalate depolymerization, expanding the range of polymers with known biological catalysts, and the utilization of derived products. We highlight several recent improvements in enzymes and reaction properties, the discovery of a wide variety of novel plastic-depolymerizing biocatalysts, and how depolymerization products can be utilized in recycling and upcycling.
生物催化剂具有解聚多种塑料的能力，正在不断涌现。改进和发现这些催化剂利用了一系列工具，包括微生物生态学研究、高通量筛选和计算指导的突变研究。在这篇综述中，我们讨论了生物解决方案在塑料回收和升级利用方面的前景，重点介绍了聚对苯二甲酸乙二醇酯解聚方面的主要进展，扩大了具有已知生物催化剂的聚合物范围，以及衍生产品的利用。我们强调了酶和反应特性的几个最新改进，发现了各种各样的新型塑料解聚生物催化剂，以及解聚产物如何在回收和升级利用中得到利用。
