Science is Fun Fridays!
This is the cotton bollworm - an agricultural pest, but a potential hero in biodegradation. Polyesterene is a huge problem in our landfills, and scientists have found plenty of insects capable of eating the plastic, but it was unclear how they were breaking it down. Biochemists have discovered four types of fungi in the guts of cotton bollworm larvae which appear to play the part. After testing each with a film of Styrofoam over 60 days, they were especially surprised by Taloromyces, which was able to grow on the film, meaning it used it as a carbon/food source. Researchers will be seeking to learn the chemical processes involved, including which enzymes, to determine if the fungi is actually digesting the plastic or just breaking it down into smaller pieces, and what the byproducts of those reactions might be.
