Abstract:
Since plastic pollution poses a persistent global environmental and public health challenge, a recent groundbreaking study has repurposed a classical organic chemistry reaction, the Lossen rearrangement, to be biocompatible within live engineered Escherichia coli for valorizing plastic waste. The exciting innovation biosynthesized a pharmaceutical compound, paracetamol (para-hydroxyacetanilide), within bacteria by utilizing a polyethylene terephthalate (PET) waste-derived substrate (PET-1) for the Lossen rearrangement. However, despite advances in synthetic biology, its deployment for plastic bioremediation is currently feasible only in controlled systems, while its application in natural environments remains uncertain, likely due to several technical, ecological, and regulatory constraints. In addition to prioritizing its industrial-scale applications, this perspective provides prospective insights into environmental applications.
