Abstract:

Bioprocessing is an important way to achieve functional and high performance polymers. Biofunctionalization of poly(ethylene terephthalate) has becoming a hot issue of textile biotechnology. In this paper, breeding of polyester decomposition microbes and the characteristics of the two main decomposing enzyme were reviewed. Finally, the general biodegradation process of polyester was summarized. Measurements of the polyester 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 polyester were presented. The study was expected to provide assistance for modifying polyester biologically in an industrial environment.

Key words: bioprocessing, boly(ethylene terephthalate), decomposing enzyme, biocatalysis
