KAUST researchers turn to mangroves in search for plastic-degrading enzymes

Summary

Researchers from King Abdullah University of Science and Technology (KAUST), in collaboration with Universidad de los Andes and others, investigated mangrove ecosystems for enzymes capable of degrading plastics like PET. They discovered that adding agricultural residues to mangrove soils increased the number of potential PET-degrading enzymes and identified a previously unknown group of salt-tolerant enzymes. The team employed metagenomics, artificial intelligence, and 3D structural analysis to study these enzymes, publishing their findings in Nature Communications. Why it matters: This research offers potential new enzymatic solutions for global plastic waste management, particularly for high-salinity industrial applications, by leveraging the unique biodiversity of environments like Saudi Arabia's Red Sea mangroves.
