Biodegradation of Polystyrene by Tenebrio molitor, Galleria mellonella, and Zophobas atratus Larvae and Comparison of Their Degradation Effects
Researchers compared polystyrene biodegradation by three insect larvae species, finding that superworms consumed the most plastic and converted it most efficiently into low-molecular-weight substances, while all three species harbored gut bacteria from the genera Enterococcus and Enterobacteriaceae that appear to drive the degradation process.

Biodegradation of aged polyethylene (PE) and polystyrene (PS) microplastics by yellow mealworms (Tenebrio molitor larvae)
Yellow mealworm larvae were able to consume and biodegrade both fresh and aged polyethylene film and polystyrene foam over a 35-day period. While aged plastics slightly slowed larval growth, the worms still broke down the plastic with help from their gut bacteria, confirmed by chemical analysis showing structural changes in the consumed plastic. This biological approach to plastic degradation could help reduce the amount of plastic waste that eventually breaks down into microplastics in the environment.
