摘要

聚酰胺（尼龙）废弃物的环境积累是一个紧迫的全球性问题。微生物酶介导的生物降解是对废弃尼龙进行可持续管理的最具吸引力和最环保的方法。然而，低效的降解率和对潜在酶和机制的有限知识阻碍了它的发展。鉴于其重要性，本文综述了尼龙酶解聚的进展，其机制，挑战和机遇。该综述可以为蛋白质工程提供信息，并促进新型尼龙降解酶的发现。

Enzymatic depolymerization of polyamides (nylons): current challenges and future directions

Environmental accumulation of polyamide (nylon) waste is a pressing global issue. Microbial enzyme-mediated biodegradation serves as the most attractive and eco-friendly approach for the sustainable management of end-of-life nylons. However, it is hampered by inefficient degradation rates and a limited knowledge of potential enzymes and mechanisms. Given its significance, this review aims to provide a comprehensive overview of the advancements in enzymatic nylon depolymerization, their mechanisms, their challenges, and their opportunities. The review can then inform protein engineering and enhance the discovery of novel nylon-degrading enzymes.

期刊介绍： Polymer Degradation and Stability deals with the degradation reactions and their control which are a major preoccupation of practitioners of the many and diverse aspects of modern polymer technology. Deteriorative reactions occur during processing, when polymers are subjected to heat, oxygen and mechanical stress, and during the useful life of the materials when oxygen and sunlight are the most important degradative agencies. In more specialised applications, degradation may be induced by high energy radiation, ozone, atmospheric pollutants, mechanical stress, biological action, hydrolysis and many other influences. The mechanisms of these reactions and stabilisation processes must be understood if the technology and application of polymers are to continue to advance. The reporting of investigations of this kind is therefore a major function of this journal. However there are also new developments in polymer technology in which degradation processes find positive applications. For example, photodegradable plastics are now available, the recycling of polymeric products will become increasingly important, degradation and combustion studies are involved in the definition of the fire hazards which are associated with polymeric materials and the microelectronics industry is vitally dependent upon polymer degradation in the manufacture of its circuitry. Polymer properties may also be improved by processes like curing and grafting, the chemistry of which can be closely related to that which causes physical deterioration in other circumstances.
