Abstract

Synthetic polymers such as plastics exhibit numerous advantageous properties that have made them essential components of our daily lives, with plastic production doubling every 15 years. The relatively low cost of petroleum-based polymers encourages their single use and overconsumption. Synthetic plastics are recalcitrant to biodegradation, and mismanagement of plastic waste leads to their accumulation in the ecosystem, resulting in a disastrous environmental footprint. Enzymes capable of depolymerizing plastics have been reported recently that may provide a starting point for eco-friendly plastic recycling routes. However, some questions remain about the mechanisms by which enzymes can digest insoluble solid substrates. We review the characterization and engineering of plastic-eating enzymes and provide some comparisons with the field of lignocellulosic biomass valorization. Expected final online publication date for the Annual Review of Chemical and Biomolecular Engineering, Volume 13 is October 2022.

生物质Valorization改进塑料回收酶的经验教训。

塑料等合成聚合物表现出许多有利的特性，使其成为我们日常生活的重要组成部分，塑料产量每15年翻一番。石油基聚合物相对较低的成本鼓励了它们的一次性使用和过度消费。合成塑料难以生物降解，塑料垃圾管理不善导致其在生态系统中积累，造成灾难性的环境足迹。最近有报道称，能够解聚塑料的酶可能为环保塑料回收路线提供一个起点。然而，关于酶消化不溶性固体底物的机制仍存在一些问题。我们综述了食用塑料酶的特性和工程，并与木质纤维素生物质的价格化领域进行了一些比较。《化学与生物分子工程年刊》第13卷预计最终在线出版日期为2022年10月。请参阅http://www.annualreviews.org/page/journal/pubdates用于修订估算。

期刊介绍： The Annual Review of Chemical and Biomolecular Engineering aims to provide a perspective on the broad field of chemical (and related) engineering. The journal draws from disciplines as diverse as biology, physics, and engineering, with development of chemical products and processes as the unifying theme.
