Core Viewpoint - The research team led by Professor Chen Xianzhong from Jiangnan University has made significant progress in the degradation of PET plastics, presenting a new integrated self-assembling multi-enzyme display platform for efficient PET waste degradation, published in the Journal of Hazardous Materials [2][3]. Group 1: PET Waste and Environmental Impact - Polyethylene terephthalate (PET) is one of the most widely produced synthetic polyesters, with its waste posing a serious threat to ecosystems due to its difficulty in natural degradation [3]. - The discovery of various PET hydrolases, such as PETase and MHETase, has provided potential for biological degradation of PET, but challenges like poor stability, difficult recovery, and high costs of free enzyme systems hinder large-scale application [3]. Group 2: Research Methodology - The research team utilized Candida tropicalis as a chassis cell, predicting potential GPI-anchored proteins through whole-genome bioinformatics analysis, identifying 22 proteins capable of anchoring foreign proteins to the cell wall [3]. - The team developed an integrated self-assembling multi-enzyme display platform (ISA-MEDP) using SpyTag/SpyCatcher and SnoopTag/SnoopCatcher protein reactions, optimizing the co-display ratio of FAST-PETase and MHETase to create FM series strains [4]. Group 3: Performance Evaluation - The enzyme activity of the best-performing FM2 strain reached 21.34 U/g dry cell weight, with a subsequent increase in enzyme activity by 10.3 times to 220.1 U/g dry cell weight through the use of inducible and repressible promoters [5]. - The ISA-MEDP catalyst demonstrated stability at 45°C for 7 days, maintaining over 50% initial activity after 7 uses, and effectively degrading various untreated post-consumer PET waste into TPA within 7 to 13 days [5]. Group 4: Funding and Acknowledgments - The research was supported by the National Natural Science Foundation and key national research projects, highlighting the importance of funding in advancing biotechnological research [7].
