ClearMicrobial 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.
Microplastics from mulching film is a distinct habitat for bacteria in farmland soil
Microplastics collected from cotton field mulch films in Xinjiang, China were analyzed by electron microscopy and 16S rRNA sequencing, revealing bacterial communities on plastic surfaces that were structurally distinct from surrounding soil, plant litter, and macroplastics. The study identifies microplastics from agricultural mulch films as novel microbial habitats with a distinct plastisphere community structure.
Integrated microbiology and metabolomics analysis reveal plastic mulch film residue affects soil microorganisms and their metabolic functions
Researchers used high-throughput gene sequencing combined with metabolomics to study how plastic mulch film residues affect soil microorganisms and their metabolic functions. They found that mulch film residues significantly altered microbial community composition and disrupted key metabolic pathways in the soil. The study reveals that plastic agricultural film left in soil can interfere with the biological processes that keep soil ecosystems healthy.

Metagenomic exploration of microbial and enzymatic traits involved in microplastic biodegradation
A metagenomic study of agricultural soil microcosms containing low-density polyethylene and polylactic acid mulch films revealed the diversity of plastic-degrading enzymes and associated microbial communities capable of microplastic biodegradation.
Dynamics of the plastisphere microbiome in agricultural soils under changing climatic conditions
Researchers monitored the microbial communities colonizing biodegradable (PBS, PBAT) and conventional polyethylene plastics buried in agricultural soils over one year under organic vs. conventional farming and current vs. projected climate conditions, finding that farming practice shaped the plastisphere microbiome more than climate, with early colonization dominated by genera known to degrade plastics.
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.
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.
The plastisphere of biodegradable and conventional microplastics from residues exhibit distinct microbial structure, network and function in plastic-mulching farmland
Researchers compared the bacterial communities that colonize biodegradable and conventional plastic microplastics in farmland soil. They found that biodegradable plastics (PBAT/PLA) and conventional polyethylene each attracted distinct microbial communities with different functions, including bacteria that could degrade plastics or cycle nutrients. The results suggest that even biodegradable plastics create unique microbial environments in soil that may affect soil health and function in unexpected ways.

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.
Biofilm Structural and Functional Features on Microplastic Surfaces in Greenhouse Agricultural Soil
Researchers studied biofilm formation on five types of microplastics in greenhouse agricultural soil over 30 days at two concentrations.

Metatranscriptomics of microbial biofilm succession on HDPE foil: uncovering plastic-degrading potential in soil communities
Using genetic analysis, researchers examined which microbial genes are active on polyethylene plastic surfaces in landfill soil versus undisturbed forest soil. They found that both communities carry genes capable of degrading plastic, with plastic-degrading enzymes being most active during early biofilm formation. The discovery that even undisturbed soils harbor plastic-degrading microbes is promising for bioremediation strategies, though the slow rate of natural breakdown means microplastics still persist in soils for very long periods.

Mechanisms of polyethylene microplastics on microbial community assembly and carbon-nitrogen transformation potentials in soils with different textures
Researchers used DNA sequencing to examine how polyethylene microplastics affect soil microbial communities and carbon-nitrogen cycling across soils with different textures. They found that microplastics significantly shifted microbial community composition and altered the abundance of genes involved in carbon and nitrogen transformation, with effects varying by soil type. The study suggests that microplastic contamination may disrupt fundamental nutrient cycling processes differently depending on soil characteristics.
