Mite-microbe gut symbiosis: Novel concept for plastic degradation and waste management
Researchers propose a novel concept for plastic biodegradation based on mite-microbe gut symbiosis, building on three years of research exploring whether soil microarthropods (mites) and their gut microbial communities could degrade plastic materials. The paper reviews existing evidence on bacterial and fungal plastic degradation and discusses preliminary findings suggesting that mites ingesting microplastics may harbor gut symbionts capable of contributing to plastic breakdown.
Molecular-Weight-Dependent Degradation of Plastics: Deciphering Host–Microbiome Synergy Biodegradation of High-Purity Polypropylene Microplastics by Mealworms
Researchers confirmed that mealworms can biodegrade polypropylene, one of the most common and persistent plastics, by working together with their gut bacteria. The study found that the worms could break down polypropylene across a range of molecular weights, though higher molecular weight plastics were harder to process. This biological degradation approach is promising for addressing microplastic pollution, as polypropylene is a major source of microplastics found in food, water, and human tissue.
Unleashing multi-omic approaches to address environmental microplastic hazards in marine polychaetes
Researchers used a multi-omic approach (metagenomics and metabolomics) to study how an environmental microplastic mixture affects the gut microbiome and metabolism of marine polychaetes, identifying disruption of specific bacterial taxa and altered metabolite profiles (indoles, flavonoids, terpenes) that indicate physiological stress.
Effects of plastic aging on biodegradation of polystyrene by Tenebrio molitor larvae: Insights into gut microbiome and bacterial metabolism
Researchers showed that UV and freeze-thaw pretreatment of polystyrene microplastics modestly improved biodegradation by mealworm larvae (Tenebrio molitor), but more notably reshaped the larvae's gut microbial communities and associated metabolic gene profiles, suggesting that plastic aging mainly affects how the gut microbiome adapts rather than dramatically changing degradation rates.
Plastics shape the black soldier fly larvae gut microbiome and select for biodegrading functions
Researchers found that black soldier fly larvae can adapt their gut microbiome to digest a wide range of plastics, shifting their microbial communities to favor biodegrading functions. This suggests the insects could serve as living incubators for discovering new plastic-breaking enzymes for industrial cleanup applications.
Earthworms Exposed to Polyethylene and Biodegradable Microplastics in Soil: Microplastic Characterization and Microbial Community Analysis
Researchers exposed earthworms to biodegradable and conventional polyethylene microplastics in natural soil and found that worms ingested both types. The biodegradable plastic showed signs of partial breakdown in the earthworm gut, while conventional polyethylene remained unchanged. Although microplastics did not significantly alter the soil or gut microbiome in this study, the results confirm that earthworms transport microplastics through soil ecosystems.

Biodegradation of various grades of polyethylene microplastics by Tenebrio molitor and Tenebrio obscurus larvae: Effects on their physiology
Mealworm larvae (Tenebrio molitor and Tenebrio obscurus) were fed different grades of polyethylene plastic to test their ability to biodegrade this common plastic. Both species could consume and partially break down all three types of polyethylene, though the process caused oxidative stress and shifted their gut bacteria. This research suggests biological degradation of plastic waste is possible, which could help reduce the environmental breakdown of plastics into harmful microplastics.
Pivotal role of earthworm gut protists in mediating antibiotic resistance genes under microplastic and sulfamethoxazole stress in soil–earthworm systems
