ClearMicroplastic accumulation in soils: Unlocking the mechanism and biodegradation pathway
Researchers reviewed how microplastics accumulate in soil and break down biologically, finding that certain microorganisms can form biofilms on plastic surfaces and use enzymes to slowly degrade the polymers — though conditions like pH, temperature, and moisture must be optimized and new plastic-degrading microbes need to be identified before this approach can be widely applied.
Interaction effects and mechanisms of microorganisms and microplastics in soil environment
This review examines how microplastics and soil microorganisms interact: microplastics disrupt soil structure, reduce water retention, and impede plant root growth, while certain bacteria and fungi can colonize and partially degrade plastic particles through a multi-step process involving colonization, fragmentation, assimilation, and mineralization. Different polymer types (PE, PP, PS, PVC, PET) attract different microbial communities, and factors like temperature, moisture, and plastic additives affect degradation rates. Understanding these interactions is key to assessing long-term soil health impacts and developing microbial strategies to reduce plastic accumulation in agricultural soils.
[Interaction between microplastics and microorganisms in soil environment: a review].
This review examines how microplastics alter soil microbial community structure and diversity, and how microorganisms in turn colonize plastic surfaces and degrade them through extracellular enzymes — with degradation efficiency dependent on polymer properties and environmental conditions.
Effect of microplastics on soil microbial community and microbial degradation of microplastics in soil: A review
This review examines how microplastics affect soil microbial communities and the potential for microbes to degrade plastic particles in soil environments. The study highlights that soil acts as a major sink for microplastics from sources like sewage sludge, agricultural mulch, and wastewater, and identifies key knowledge gaps including the need for better monitoring of microplastic sources and exploration of microbial biodegradation potential.

This review examines how microplastic pollution affects soil organic carbon cycling, covering direct participation in carbon processes and indirect effects on soil physicochemical properties and microbial communities. The authors synthesize mechanisms by which microplastics influence organic carbon formation, mineralization, and sequestration in terrestrial ecosystems.
Microplastic effects on carbon cycling processes in soils
Researchers reviewed how microplastics affect carbon cycling processes in soils, including their influence on microbial activity, plant growth, and litter decomposition. Since microplastics are themselves carbon-based materials, they can directly alter soil carbon stocks while also indirectly shifting microbial communities. The study calls for a major research effort to understand the widespread effects of microplastics on soil functioning and terrestrial ecosystem health.
Microbial remediation of microplastic-contaminated soil, focusing on mechanisms, benefits, and research gaps
This systematic review examines microbial bioremediation of microplastic-contaminated soils, covering the sources and distribution of soil microplastics, their physicochemical interactions with soil microbiomes, and the mechanisms by which soil-dwelling bacteria and fungi degrade plastic polymers.
Systematical review of interactions between microplastics and microorganisms in the soil environment
This review explores interactions between microplastics and microorganisms in soil environments. Researchers found that microplastics pose a threat to the survival and reproduction of soil microbiota, but that soil microorganisms also show potential for degrading and mineralizing microplastic particles, suggesting possible biological pathways for microplastic remediation in terrestrial ecosystems.

The Spatiotemporal Successions of Bacterial and Fungal Plastisphere Communities and Their Effects on Microplastic Degradation in Soil Ecosystems
Researchers tracked how bacterial and fungal communities colonize microplastic surfaces in soil over time, finding that the surrounding soil type had the strongest influence on which microbes grew on the plastics. The microbial communities on microplastics were less diverse and less stable than those in the surrounding soil, but they attracted microbes with a higher capacity to break down organic carbon. The study suggests that microplastic surfaces become hotspots for carbon metabolism in soil ecosystems.
Microplastics alter soil carbon cycling: Effects on carbon storage, CO 2 and CH 4 emission and microbial community
This systematic review examines how microplastics in soil affect carbon cycling, including greenhouse gas emissions and carbon storage. The effects depend heavily on plastic type and size, with biodegradable plastics generally having a bigger impact. Understanding these soil-level changes matters because disrupted carbon cycles can worsen climate change, which in turn affects the food and water systems we all depend on.

Influence of biodegradable microplastics on soil carbon cycling: Insights from soil respiration, enzyme activity, carbon use efficiency and microbial community
Researchers investigated how biodegradable microplastics affect carbon cycling in soil by measuring respiration, enzyme activity, and microbial communities over 64 days. They found that certain biodegradable plastics, particularly polyhydroxyalkanoates, dramatically increased soil carbon emissions by up to 665% and significantly altered microbial community structure. The study suggests that even biodegradable plastics can substantially disrupt soil ecosystem processes when they break down into microplastic-sized particles.
Regulatory path for soil microbial communities depends on the type and dose of microplastics
Researchers compared how six types of microplastics at different concentrations affect soil microbial communities, testing both conventional and biodegradable plastics. They found that biodegradable microplastics had a greater impact on soil carbon and nitrogen levels than conventional ones, and that the type and dose of microplastic determined which microbial groups were most affected. The findings suggest that even so-called biodegradable plastics can significantly alter soil ecosystems when they break down into microplastic-sized particles.
