Environmental Identification of Novel Enzymes for Polyurethane and Polyamide Degradation
Angewandte Chemie International Edition, EarlyView.Heteroatom‐containing plastics such as polyurethanes and nylons are produced at scale yet remain largely unrecycled. Biocatalysts offer a promising route to depolymerization under mild conditions. Here, we present a screening platform for the discovery of novel polyurethane‐ and nylon‐degrading enzymes from environmental samples and demonstrate ...
