Biodegradation of polystyrene by intestinal symbiotic bacteria isolated from mealworms, the larvae of Tenebrio molitor
AI summary Read the abstract
This study found that the gut microbiome of mealworm larvae (Tenebrio molitor) harbors a diverse community of polystyrene-degrading bacteria, suggesting that intestinal symbionts of these insects could be harnessed as a biological strategy for breaking down one of the world's most persistent plastic pollutants.
Bacterial identification shows that a broad spectrum of bacteria decomposing polystyrene coexists in the intestinal tract of mealworms.
