摘要

En 中文

塑料的惰性、耐久性、低成本和广泛适用性使其成为我们生活中不可或缺的材料。这种依赖性导致了塑料物品数量不断增加，其中相当一部分被填埋或倾倒入环境中，从而影响陆地和水生生态系统。在塑料材料中，聚烯烃最为丰富，且因其含有强C-C和C-H键而难以生物降解。然而，尽管有限，自然界中聚烯烃的生物降解已有报道。这一观察结果引发了关于微生物聚烯烃降解的研究。通过设计含工程酶的合成微生物群落，该过程更高效和精准的版本也可能在实验室中开发。在本综述中，我们讨论了开发此类微生物群落及鉴定新型聚烯烃降解微生物的策略，以及具有更高催化效率的聚乙烯氧化酶的工程化。最后，将概述用于设计能够成功实现聚烯烃生物修复的合成微生物群落的不同技术。
