Summary

Researchers compared the gut microbiomes of mealworms fed polystyrene plastic versus corn straw and found strikingly similar microbial community responses to both diets. The findings suggest that the ability of mealworm larvae to break down plastics likely evolved from ancient biological mechanisms originally designed to digest natural plant fibers like lignocellulose. The study points to mealworm gut bacteria as a potential resource for developing biological plastic degradation strategies.

Polymers

The high similarity of gut microbiomes adapted to biodegradation of PS and CS indicated the plastics-degrading ability of the T. molitor larvae originated through an ancient mechanism that degrades the natural lignocellulose. Video Abstract.
