ABSTRACT Polyethylene Terephthalate (PET) is one of the most widely used thermoplastic polymers, renowned for its exceptional physical, chemical, and mechanical properties, making it a popular choice various applications. On other hand, PET major part plastic waste, therefore, research devoted to degradation at forefront developing recycling methods. This fundamental study focuses on enzymatic model substrate using range established cutinases (PHL‐7, HiC, LCC WT , ICCG ) alongside IsPETase under varying conditions. A comprehensive evaluation was conducted investigate impact reaction temperatures, polymer pretreatment methods, dual‐enzyme systems enhancing biodegradation. The techniques employed, targeting crystallinity reduction, adsorption, exchange‐surface modifications, proved pivotal in accelerating process improving yield monomers. novelty this work lies systematically studying effects combined strategies degradation. Furthermore, integration multiple enzymes enhances overall efficiency hydrolysis. These findings provide comparative framework that integrates enzyme performance with effects.

Plastics have become an indispensable material in many fields of human activities, with production increasing every year; however, most the plastic waste is still incinerated or landfilled, and only 10% new recycled even once. Among all plastics, polyethylene terephthalate (PET) produced polyester worldwide; ethylene glycol (EG) one two monomers released by biorecycling PET. While research focuses on bacterial EG metabolism, this work reports ability Saccharomyces cerevisiae nine other common laboratory yeast species not to consume EG, but also produce glycolic acid (GA) as main by-product. A two-step bioconversion GA S. was optimized a design experiment approach, obtaining 4.51 ± 0.12 g l-1 conversion 94.25 1.74% from 6.21 0.04 EG. To improve titer, screening biodiversity identified Scheffersomyces stipitis best producer, 23.79 1.19 (yield 76.68%) bioreactor fermentation, single-step bioprocess. Our findings contribute laying ground for upcycling strategies yeasts.
