Screening the LDPE microplastic degradation potential of the epigeic earthworm species reported from the district Hamirpur of Himachal Pradesh
Summary
Researchers screened three epigeic earthworm species from the Hamirpur district of Himachal Pradesh, India, for their ability to degrade low-density polyethylene microplastics in soil. The study investigates the potential of earthworm-mediated bioremediation as an in-situ approach to reducing microplastic pollution in agricultural soils.
Microplastic pollution has emerged as an issue of global environmental concern, posing significant threats to ecosystem as well as human health. Earthworm species belong to phylum Annelida and are known to act as an essential tool for bioremediation. They act as vital components of soil ecosystems, play a crucial role in decomposition and soil health maintenance. They have potential to degrade organic and inorganic waste to much extent which help in compacting the soil pollution. This research investigates the microplastic degradation potential of epigeic earthworm species Bimastos parvas, Perionyx excavatus and Eisenia fetida respectively. It contributes to the broader understanding of the ecological roles of earthworm species in combating microplastic pollution and underscores the importance of considering soil fauna as a beneficial entity for bioremediation strategies with context to the waste management and soil health.

Microplastics in Agricultural Soil: Fate, Impacts, and Bioremediation by Earthworms
This review examines how microplastics accumulate in agricultural soils and the role earthworms may play in breaking them down. Researchers found that microplastics can harm soil health by disrupting microbial communities, enzyme activity, and nutrient availability, but that earthworms can enhance microplastic degradation through their digestive processes and the microorganisms in their gut. The study suggests that earthworm-based bioremediation could be a practical strategy for reducing microplastic contamination in farmland.
Potential Use of Earthworms to Enhance Decaying of Biodegradable Plastics
Researchers examined the potential of earthworms to accelerate the biodegradation of both conventional and biobased biodegradable plastics in soil, finding that earthworm activity can enhance the physical fragmentation and microbial degradation of some polymers, though effectiveness varies significantly by polymer type. The study suggests earthworm-assisted composting as a partial strategy to reduce agricultural plastic pollution.
Decay of low-density polyethylene by bacteria extracted from earthworm's guts: A potential for soil restoration
Researchers isolated bacteria from earthworm guts that were able to degrade low-density polyethylene, demonstrating that intestinal microbes from soil invertebrates may play a role in plastic breakdown. The findings suggest that earthworm gut microbiomes are a reservoir of plastic-degrading bacteria with potential applications for bioremediation of LDPE-contaminated soils.
Enhancing the biodegradability and environmental impact of microplastics utilizing Eisenia fetida earthworms with treated low-density polyethylene for sustainable plastic management
Researchers used Eisenia fetida earthworms to improve the biodegradability of low-density polyethylene (LDPE) microplastics in soil, testing whether earthworm-mediated soil processing could enhance the breakdown of this persistent polymer. Earthworm activity increased LDPE fragmentation and promoted microbial colonization of plastic surfaces, suggesting vermicomposting as a strategy for managing soil plastic contamination.
Fragmentation and depolymerization of microplastics in the earthworm gut: A potential for microplastic bioremediation?
Researchers explored whether earthworms can break down microplastics in soil by passing them through their digestive systems. They found that earthworms fragmented and partially broke down polyethylene and biodegradable plastic particles, reducing their size and altering their chemical structure. This suggests earthworms could play a role in naturally reducing microplastic contamination in soil, though more research is needed to understand whether the smaller fragments pose their own risks.
