ClearThe 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.
Deciphering 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.
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.
Large-scale omics dataset of polymer degradation provides robust interpretation for microbial niche and succession on different plastisphere
Researchers generated a large-scale microbiome and metabolome dataset from five biodegradable polymer types, revealing that microbial communities converge to polymer-specific compositions during degradation and follow distinct succession stages from initial colonization through biofilm formation.
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.
Analysis of 16S rRNA amplicon data illuminates the major role of environment in determining the marine plastisphere microbial communities
Researchers analysed 16S rRNA amplicon data from marine plastisphere communities, finding that environmental factors play the dominant role in determining the microbial communities that colonise microplastic surfaces in marine ecosystems.

Researchers studied the short-term colonization dynamics of microbial communities (plastisphere) forming on six plastic polymer types submerged in marine waters in South Australia, finding polymer-type-specific differences in prokaryotic community composition over four weeks.
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.
Effects of microplastics on soil microbiome: The impacts of polymer type, shape, and concentration
Researchers examined how different microplastic polymer types, shapes, and concentrations affected soil bacterial communities, finding that these physical characteristics induced distinct shifts in soil microbiome composition and diversity.
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.
Analysis of 16S rRNA amplicon data illuminates the major role of environment in determining the marine plastisphere microbial communities
By reanalyzing publicly available microbiome data from marine microplastics collected at multiple ocean locations, this study found that the surrounding water environment shapes the community of microbes living on plastic surfaces (the plastisphere) more strongly than the type of plastic polymer does. While both location and polymer type matter, once environmental differences were accounted for, polymer type alone had no statistically significant effect on microbial diversity. This is important because microplastics can carry and transport harmful microbes across vast ocean distances, and understanding what controls those communities helps assess the ecological risk.
An In Situ Study to Understand Community Structure of Estuarine Microbes on the Plastisphere
Researchers performed 16S rRNA sequencing on biofilms from three microplastic polymer types and glass bead controls deployed in Baltimore Inner Harbor over 28 days, finding that plastisphere communities were taxonomically distinct from free-living microbial communities but that polymer type did not significantly differentiate community composition, with Cyanobacteria, Planctomycetes, and sulfate-reducing bacteria among the notable colonizers.
Dynamic evolution of microbial colonization on indoor microplastics: polymer diversity-driven co-occurrence networks and health risks
Researchers simulated 90 days of indoor microplastic exposure to study how different polymer types, aging, and morphology influence microbial colonization on microplastic surfaces. They found that polymer diversity shaped microbial co-occurrence networks and that the resulting plastisphere communities harbored potential human pathogens.
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.
Relative Influence of Plastic Debris Size and Shape, Chemical Composition and Phytoplankton-Bacteria Interactions in Driving Seawater Plastisphere Abundance, Diversity and Activity
This study evaluated the relative influence of plastic debris size, shape, chemical composition, and environmental conditions on the microbial communities colonizing ocean plastics (the plastisphere). Results showed that multiple plastic properties and environmental factors jointly shape which microorganisms colonize plastic surfaces in the marine environment.
Plastisphere assemblages differ from the surrounding bacterial communities in transitional coastal environments
Researchers found that bacterial communities colonizing plastic particles (the plastisphere) in Portuguese estuarine and beach environments were significantly different from those in surrounding water and sediments, with plastic type and environmental conditions influencing microbial community composition.
The “Plastisphere” of Biodegradable Plastics Is Characterized by Specific Microbial Taxa of Alpine and Arctic Soils
Microbial communities colonizing biodegradable plastics in soil (the plastisphere of biodegradable materials) were characterized and compared to communities on conventional non-biodegradable plastics and bulk soil. Biodegradable plastic surfaces hosted distinct microbial assemblages enriched in polymer-degrading taxa, showing that material type shapes the plastisphere community even for plastics designed to decompose.
Some Microbiological Characteristics of the Biofilm on the Surface of Pre-Production Pellets of Polypropylene Microplastics after Short Exposure in Soil
After 30 days of burial in residential soil, polypropylene microplastic pellets developed distinct surface biofilms with microbial communities different from those on quartz sand and from the surrounding soil. The colonization of microplastic surfaces by soil microbes (forming a 'plastisphere') is significant because these biofilms can alter how microplastics move through soil and may carry pathogens or antibiotic resistance genes into the environment.
Microbial Diversity of the Surface of Polypropylene and Low Density Polyethylene‐Based Materials (Plastisphere) From an Area Subjected to Intensive Agriculture
Researchers analyzed the microbial communities colonizing polypropylene and polyethylene plastic debris from an agricultural landfill site. They found that while overall bacterial diversity was similar between plastic surfaces and surrounding soil, the plastic-associated communities had distinct compositions with higher proportions of certain bacterial groups. The study suggests that these plastisphere communities may be actively degrading plastic additives and could harbor potential plastic-degrading organisms.

Interactive effects of soil characteristics and polymer types reveal patterns of denitrifying bacteria enrichment in the soil plastisphere
A field study examined how soil characteristics (texture, organic matter, pH) and polymer type interact to determine microplastic persistence and mobility in agricultural soils. The results show that soil properties are as important as plastic type in predicting environmental fate.
Environmental exposure more than plastic composition shapes marine microplastic‐associated bacterial communities in Pacific versus Caribbean field incubations
Researchers incubated six types of household plastic polymers in Pacific and Caribbean coastal waters to study the bacterial communities that form on microplastics. They found that geographic location and exposure time were far more important than plastic type in shaping these microbial communities. The study identified a core plastisphere of 57 bacterial variants common across all conditions, suggesting environmental context plays a bigger role than plastic composition in microplastic colonization.
