Scientists Engineer New Plastic-Eating Enzyme

Apr 28, 2022 by News Staff

Plastic waste poses an ecological challenge and enzymatic degradation offers one, potentially green and scalable, route for polyesters waste recycling....

Knott et al. created a two-enzyme system for PET deconstruction, which employs one enzyme (PETase) to convert the polymer into soluble intermediates and another enzyme (MHETase) to produce the constituent PET monomers. This SEM image shows amorphous PET film after 96 h enzyme treatment at 30 degrees Celsius. Image credit: Knott et al., doi: 10.1073/pnas.2006753117.
