摘要
为实现生物加工高聚物的功能化和高性能化,需利用生物技术对聚酯进行亲水化处理。为此,综述了聚酯分解菌的选育现状、2种主要分解酶的特征,重点阐述了生物催化对聚酯结构性能影响的评价和分解产物形成的检测,总结了聚酯的生物降解过程,并展望了聚酯生物加工技术的发展方向。认为先进菌种选育、微生物培养和酶工程技术的应用,将有助于得到更高效和更具工业适应性的生物催化剂,形成具有应用价值的聚酯生物加工技术。
Bioprocessing is an important way to achieve functional and high performance polymers.Biofunctionalization of poly（ ethylene terephthalate）（ PET） has been a hot issue of textile biotechnology.In this paper, breeding of PET decomposition microbes and the characteristics of the two main decomposing enzymes were reviewed. Finally, the general biodegradation process of PET was summarized. Measurement of the PET substrate structural performance and formation of breakdown products after the biocatalysis processes were further discussed. Moreover,prospects for development direction of biological processing technology for PET were presented. The study was expected to provide assistance for modifying polyesterbiologically in an industrial environment.
