ClearSources, interactions, influencing factors and ecological risks of microplastics and antibiotic resistance genes in soil: A review
Microplastics in soil serve as hotspots for antibiotic resistance genes, with the plastisphere — the microbial community colonizing plastic surfaces — facilitating horizontal gene transfer of resistance markers. Key factors driving this interaction include microplastic properties, soil chemistry, and agricultural practices, though research in soil environments is still at an early stage compared to aquatic systems.
soil plastisphere: The nexus of microplastics, bacteria, and biofilms
This commentary examines how microplastics in soil create new microbial ecosystems called the plastisphere, where bacteria colonize plastic surfaces and form biofilms. Researchers discuss how microplastics can carry harmful pathogens and contaminants through soil and into water systems. The study emphasizes the urgent need to better understand how bacteria adapt to these microplastic-rich environments, given the implications for ecosystem and human health.
Soil plastispheres as hotspots of antibiotic resistance genes and potential pathogens
Researchers investigated microbial communities and antibiotic resistance genes on microplastic surfaces (the plastisphere) in soil environments. They found that plastispheres harbor enriched levels of potential pathogens and antibiotic resistance genes compared to surrounding soil, and that adding manure or increasing temperature and moisture further amplified these concerning microbial communities.
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.
Viruses in the era of microplastics and plastispheres: Analytical methods, advances and future directions
This review examines how viruses interact with microplastics in the environment, including how viral particles attach to plastic surfaces and what this means for human and environmental health. Microplastics can carry viruses across water environments, and the biofilms that form on plastic surfaces create conditions for viral survival and gene transfer. These findings raise concerns that microplastics could serve as vehicles for spreading disease-causing viruses through water systems.
Fate and transport of biological microcontaminants bound to microplastics in the soil environment
This review explores how microplastics in soil can carry biological contaminants like antibiotic resistance genes, small RNA molecules, and pathogenic viruses. Unlike chemical pollutants, these biological hitchhikers on microplastic surfaces remain understudied, especially in terrestrial environments. Understanding this transport mechanism matters because contaminated microplastics in agricultural soil could introduce harmful biological agents into the food chain.
Soil microplastics pollution can reduce viral abundance and have less consistent impacts on bacteria
Researchers exposed soils containing natural microbial communities to polyethylene and PVC microplastics and found that both types consistently reduced viral abundance, while effects on bacteria were more variable, suggesting microplastic pollution may alter the balance of microbial communities that regulate soil processes.
Effects of agricultural inputs on soil virome-associated antibiotic resistance and virulence: A focus on manure, microplastic and pesticide
Researchers studied how agricultural inputs including manure, microplastics, and pesticides affect virus communities in soil and their potential to carry antibiotic resistance genes. They found that manure application significantly increased both viral diversity and the abundance of resistance and virulence genes carried by viruses. The study reveals that soil viruses may play a previously underappreciated role in spreading antibiotic resistance through agricultural ecosystems.

Microplastics and soil microbiomes
This review examines the two-way relationship between microplastics and soil microbiomes: how microplastics alter microbial community structure and function, and how soil microbes in turn affect the behavior of microplastics. Researchers found that microplastics can shift microbial communities and disrupt key ecosystem processes like nutrient cycling. The study also discusses how certain soil microbes may enhance the degradation of microplastics, pointing to potential natural remediation pathways.

Metagenomic analysis of plastisphere communities on microplastics collected from five freshwater sites revealed diverse viral communities including phages and potential animal pathogens, with plastic-associated viromes differing from those in surrounding water. The study identifies microplastics as previously overlooked carriers of viral diversity and potential environmental health risks in aquatic ecosystems.
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.
The formation of specific bacterial communities contributes to the enrichment of antibiotic resistance genes in the soil plastisphere
Researchers used metagenomic approaches to study how microplastic surfaces in soil become enriched with antibiotic resistance genes through the formation of specific bacterial communities. The study tested three types of microplastics at two particle sizes and found that antibiotic resistance gene abundances significantly increased in the plastisphere compared to surrounding soil. Evidence indicates that microplastics in soil may serve as hotspots for the spread of antibiotic resistance.
Soil viral–host interactions regulate microplastic-dependent carbon storage
Researchers discovered that microplastics in soil affect carbon storage by changing how viruses and bacteria interact underground.
