Researchers at Duke University are investigating whether certain bacteria can degrade microplastics, the tiny plastic particles polluting oceans, soil and the food chain. The team is assessing the ability of Pseudomonas stutzeri to digest polyethylene terephthalate (PET), a strong, transparent and lightweight plastic used in beverage containers and food packaging. Thermus thermophilus is being evaluated for its potential to degrade plastic more efficiently in warm environments.

A component of their research involves bioengineering techniques designed to help the bacteria work faster. Additionally, the group is developing a solar-powered device to house the bacteria as they process plastic in polluted areas. The long-term goal is to transform degraded plastic into new, reusable materials, thus promoting recycling over accumulation in nature.
