Scientists from Kiel University in Germany have uncovered a deep-sea enzyme called PET46 capable of continuously degrading PET plastic, commonly found in plastic bottles. PET46 possesses unique properties, breaking down both long-chain and short-chain PET molecules, making it valuable for biotechnology applications. This breakthrough is a part of the PLASTISEA project and offers insights into addressing plastic waste degradation in marine and terrestrial environments. PET plastic, short for polyethylene terephthalate, is a widely used type of plastic known for its transparency, lightweight properties, and recyclability, primarily used in bottles, containers, and synthetic fibers.
