Summary

This review examines how PETase enzymes can be used to biodegrade plastic waste, particularly polyethylene terephthalate, which is one of the most widely used plastics globally. Researchers discuss recent advances in modifying PETase enzymes for improved efficiency and establishing sustainable synthesis platforms. The study suggests that enzymatic biodegradation offers a promising biological solution to the growing plastic pollution crisis.

As a versatile chemical material, plastic is widely used in all aspects of human society with its excellent performance, in the development process of plastics, due to its difficult to degrade characteristics, coupled with the initial formation of a control system, the harm of plastics to the environment is gradually revealed. The current global plastic crisis poses significant environmental challenges, impacting both human health and marine ecosystems. Plastic waste circulates worldwide, exacerbating the issue. Recent advancements in microbiological plastic degradation methods offer promising solutions. These approaches encompass modifying PETase enzymes, establishing a sustainable PETase synthesis platform, and reevaluating PETase variants for enhanced plastic degradation and heightened thermal stability within plant compost environments. Additionally, the implementation of pollution control measures across agriculture, industry, and governmental policies is crucial. This comprehensive study highlights strategies to bolster PETase efficiency, aligning with present environmental plastic degradation needs. It holds potential for combatting plastic pollution, promoting closed-loop plastic cycles, and charting a course for future research endeavors.
