摘要:

聚羟基脂肪酸酯(PHA)作为一种可生物降解的生物塑料,具有理化性质与传统塑料相似且对环境友好的特点,已逐渐成为传统塑料的替代品。在PHA制品使用寿命结束之后,应当考虑对PHA废物进行合理地处置,以减轻环境压力。本文介绍了PHA的种类、性质与应用,综述了PHA在不同环境/过程中的生物降解情况、PHA生物降解过程中的关键微生物和酶、生物降解的机制以及与生物降解相关的标准,旨在为改善PHA制品生物降解性能和优化PHA废物管理和处置策略提供理论参考。

Abstract:

Polyhydroxyalkanoate (PHA) as a biodegradable plastic has been gradually developed into an alternative to traditional plastics due to its similar physicochemical properties to traditional plastics together with environmentally friendly characteristics. Upon reaching the end of their lives, some consideration should be given to reasonably dispose PHA wastes to alleviate environmental pressures. This review paper introduced the categories, properties and applications of PHA. The biodegradation of PHA in different environments or processes, functional microorganisms, and enzymes, as well as the mechanism and standards related to biodegradation were also summarized. This paper aimed to provide theoretical references for improving the biodegradability of PHA products and optimizing PHA waste management and disposal strategies.

Key words: polyhydroxyalkanoates, biodegradation, aerobic, anaerobic, biodegradation mechanism
