Scientists have developed a solution to tackle plastic waste, inspired by mussels. Researchers at Rice University created bioengineered microorganisms that can stick to surfaces, specifically designed to break down polyethylene terephthalate (PET), a common type of plastic that can take centuries to decompose. The team used genetic code expansion to modify bacteria, introducing a natural amino acid found in mussels to enhance their ability to adhere to PET surfaces. The engineered bacteria showed a 400-fold increase in adhesion to PET substrates and can break down plastic significantly overnight. This technology can also be applied to prevent biofouling, a major problem in industries like shipping and water treatment. The researchers believe this breakthrough can have far-reaching implications, including healthcare, where modified proteins could be used to inhibit bacterial adhesion on medical devices. The discovery has the potential to transform bioengineering applications and solve real-world problems, such as the growing issue of plastic pollution.
