摘要:

随着塑料污染治理需求日益紧迫,能够从源头防治塑料污染的生物降解塑料得到了大力发展。兼具有良好韧性、耐冲击性和生物降解性的聚对苯二甲酸⁃己二酸丁二酯(PBAT)成为消费量最高的生物降解塑料之一,广泛用于生物降解膜袋类制品和一次性餐饮具等领域。本文综述了目前已知的PBAT降解菌和降解酶及其降解能力,总结了影响微生物降解速率的主要因素,阐述了PBAT的生物降解机理,并对降解能力标准化评价方法、PBAT降解菌剂和PBAT高效降解酶的开发和应用提出展望。

Abstract:

The urgent need to control global plastic pollution has driven the vigorous development of biodegradable plastics as a solution to prevent waste at the source. Poly(butylene adipate⁃co⁃terephthalate) (PBAT), renowned for its flexibility, impact resistance, and biodegradability, has emerged as one of the most widely used polymers in this class. It is extensively applied in producing biodegradable films, packaging materials, and disposable tableware. This review comprehensively summarizes the current progress in PBAT biodegradation. The known microbial strains and enzymes capable of degrading PBAT were categorized, and their respective degradation efficiencies were evaluated. The key environmental and material factors influencing the degradation rate were discussed, and the underlying microbial mechanisms were elucidated. Finally, critical challenges and future directions were addressed, including the need for standardized evaluation methods, the development of specialized microbial consortia, and the exploration of efficient enzymatic systems for large⁃scale bioremediation applications.

Key words: poly(butylene adipate terephthalate), biodegradation, degrading bacteria, enzymes
