Researchers at Rice University have developed a groundbreaking bioengineering method that can break down PET (polyethylene terephthalate) plastic, a common plastic used in packaging that takes centuries to decompose. Inspired by the adhesive properties of mussels, the scientists have engineered microorganisms that can stick to plastic surfaces and break them down. The innovation could revolutionize environmental cleanup efforts, which are currently slow and inefficient. The researchers used genetic code expansion technology to create bacteria enhanced with an amino acid found in mussels, which gives them a powerful adhesive quality. Once adhered to the PET plastic, the bacteria break down the plastic into smaller fragments using an enzyme designed to target the plastic. This method could be used in large-scale environmental cleanup efforts, and also has applications in preventing biofouling and medical use. The research offers new hope for reducing plastic pollution and could transform environmental cleanup efforts worldwide.
