ClearDeciphering the Mechanisms Shaping the Plastisphere Microbiota in Soil
Researchers characterized bacterial communities colonizing biodegradable and conventional microplastics in soil, finding that polymer type and biodegradability shaped distinct plastisphere communities, with deterministic processes playing a stronger role in community assembly than in surrounding soil.
Microplastics reduce soil microbial network complexity and ecological deterministic selection
Researchers found that microplastics reduce soil microbial network complexity and shift community assembly from deterministic to more stochastic processes, suggesting that microplastic pollution may fundamentally alter microbial ecological interactions in terrestrial systems.
The SpatiotemporalSuccessions of Bacterial and FungalPlastisphere Communities and Their Effects on Microplastic Degradationin Soil Ecosystems
Researchers explored spatiotemporal succession of bacterial and fungal plastisphere communities on three microplastic types across three soil types over multiple time periods, finding that colonization environment was the dominant driver of plastisphere microbiome assembly, followed by polymer type and incubation time.
Microplastic polymer properties as deterministic factors driving terrestrial plastisphere microbiome assembly and succession in the field
Researchers incubated five common microplastic polymer types in landfill soil for 14 months and used 16S rRNA sequencing to characterize the plastisphere communities that assembled on each polymer. Polymer type was a significant deterministic factor in plastisphere microbiome composition, which differed from surrounding soil communities and varied over time.
Biodegradable microplastics enhance soil microbial network complexity and ecological stochasticity
Researchers found that biodegradable microplastics increased soil microbial network complexity and shifted community assembly toward more stochastic processes, suggesting they reshape soil ecosystems differently than conventional plastics.
The Terrestrial Plastisphere: Diversity and Polymer-Colonizing Potential of Plastic-Associated Microbial Communities in Soil
Soil-buried plastic debris harbored microbial communities clearly distinct from surrounding bulk soil and from aquatic plastisphere communities, with a core set of plastic-colonizing taxa including Proteobacteria and Actinobacteria detected across both polymer types tested, suggesting that terrestrial plastisphere colonization follows predictable ecological rules.
Contribution of stochastic processes to the microbial community assembly on field‐collected microplastics
Researchers found that stochastic processes played a greater role than deterministic factors in shaping bacterial community assembly on field-collected microplastics in the Hangzhou Bay estuary, challenging assumptions about the distinctiveness of the plastisphere.
Soil plastisphere: Exploration methods, influencing factors, and ecological insights
This review explored the soil plastisphere, examining how microplastics serve as substrates for microbial colonization in terrestrial ecosystems, and identified key factors influencing plastisphere formation, composition, and ecological functions in soil environments.
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.
Niche vs. habitat: Insights of aging microplastics and wetland types on bacterial community assembly
Researchers studied how bacterial communities assemble on microplastic surfaces (plastispheres) versus surrounding soil in three types of wetlands using low-density polyethylene. They found that wetland habitat type had a stronger influence on bacterial diversity patterns than whether the plastic was virgin or aged, with plastisphere communities showing lower diversity and more stochastic assembly compared to soil communities.
Microplastics increase soil microbial network complexity and trigger diversity-driven community assembly
Researchers found that microplastics in soil increased bacterial network complexity and shifted microbial community assembly in a diversity-dependent manner, with high-density polyethylene causing more harm to plant growth than polystyrene or polylactic acid particles.
Distinct spatiotemporal succession of bacterial generalists and specialists in the lacustrine plastisphere
A study of lacustrine plastisphere bacteria found that generalist species were initially more abundant than specialists on colonizing microplastics but declined over time, with deterministic processes driving generalist assembly and stochastic processes driving specialist assembly.

Soil pH had a stronger influence than arsenic contamination on shaping the bacterial communities colonizing microplastic surfaces (plastisphere) in contaminated soils, highlighting pH as a key driver of plastisphere ecology.
Year-Long Microbial Succession on Microplastics in Wastewater: Chaotic Dynamics Outweigh Preferential Growth
Researchers conducted a year-long study of microbial succession on microplastics in a wastewater treatment plant, finding that chaotic community dynamics outweigh any preferential colonization by plastic-specific microorganisms, challenging the concept of a consistent plastisphere microbiome.
Edaphic Gradients Reshape Microbial Microenclaves Assembly within Plastispheres
Researchers sampled microplastics and surrounding soils at 27 urban wetland sites in China to study how bacteria colonize plastic surfaces, forming communities known as plastispheres. They found that plastispheres selectively recruit soil bacteria but harbor only 52-69% of the bacterial diversity found in adjacent soil. The study reveals that soil nutrient levels and moisture conditions strongly influence how these microplastic-associated microbial communities assemble.

Researchers compared microplastic effects on soil organic matter dynamics and bacterial communities across contrasting soil environments, finding that the type of microplastic polymer and soil conditions together determine whether microbial activity and carbon cycling are stimulated or suppressed.
Microplastics negatively affect soil fauna but stimulate microbial activity: insights from a field-based microplastic addition experiment
A meta-analysis of microplastic studies found that microplastics negatively affect soil fauna abundance and diversity while stimulating soil microbial activity, based on data from multiple laboratory experiments. The opposing effects on fauna and microbes suggest that microplastics can shift soil community structure in ways that alter ecosystem functions like decomposition and nutrient cycling.
The structure and assembly mechanisms of plastisphere microbial community in natural marine environment
Researchers investigated how microbial communities colonize different types of microplastic surfaces in natural marine environments over an eight-week period. They found that the composition of these plastic-associated microbial communities, known as the plastisphere, was shaped more by environmental conditions and time than by the specific type of plastic. The study provides new understanding of the ecological processes governing how microorganisms assemble on ocean plastic debris.
