ClearAlteration of microbial mediated carbon cycle and antibiotic resistance genes during plastisphere formation in coastal area
Researchers investigated how microplastic surfaces in coastal environments develop biofilm communities, known as the plastisphere, and whether these biofilms enrich antibiotic resistance genes. The study found that incubation time, habitat type, and microplastic aging state all significantly influenced biofilm composition, and that aged microplastics accumulated more antibiotic resistance genes than new ones, suggesting microplastics may serve as vectors for spreading resistant bacteria.
Marine plastisphere selectively enriches microbial assemblages and antibiotic resistance genes during long-term cultivation periods
Researchers placed four types of common microplastics in a marine environment for over 100 days and found that bacterial communities and antibiotic resistance genes accumulated on the plastic surfaces over time. PVC microplastics were particularly effective at concentrating resistance genes, and a key gene-transfer element was found on all plastic types. These results show that microplastics floating in the ocean act as hotspots for antibiotic-resistant bacteria, which could eventually reach humans through seafood or water.
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.
(Nano)microplastics promote the propagation of antibiotic resistance genes in landfill leachate
Researchers found that (nano)microplastics in municipal landfill leachate actively promote the spread of antibiotic resistance genes, highlighting landfill sites as dual reservoirs of plastic pollution and antimicrobial resistance threats.
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.
Antibiotic resistance in plastisphere
Researchers reviewed antibiotic resistance in the plastisphere — the microbial community colonizing plastic surfaces in aquatic environments — finding that plastic properties and aging influence the enrichment and horizontal transfer of antibiotic resistance genes, and that aged microplastics pose elevated risks due to increased adsorption of resistant bacteria.
Microbial diversity and potential pathogens associated with the plastisphere on beaches of Rio de Janeiro, Brazil
Researchers analyzed the microbes living on plastic debris collected from beaches in Rio de Janeiro, finding that both polypropylene and polyethylene plastics harbored communities containing potential human and marine pathogens as well as bacteria carrying antibiotic resistance genes. The study confirms that ocean plastics can transport dangerous microorganisms across long distances, posing risks to human health and marine biodiversity.
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.
Comprehensive profiling and risk assessment of antibiotic resistomes in surface water and plastisphere by integrated shotgun metagenomics
Researchers used shotgun metagenomics to compare antibiotic resistance genes in surface water versus the biofilms that form on microplastic surfaces, known as the plastisphere. They found that microplastics harbored distinct microbial communities with different antibiotic resistance profiles compared to surrounding water. The study raises concerns that microplastics may serve as vehicles for spreading antibiotic resistance in aquatic environments.
16S rRNA gene sequence analysis of the microbial community on microplastic samples from the North Atlantic and Great Pacific Garbage Patches
Researchers compared microbial communities living on microplastics collected from the North Atlantic and Great Pacific Garbage Patches, finding distinct plastisphere communities shaped by ocean region and plastic type. Understanding which microbes thrive on ocean plastic helps assess the risk of harmful or antibiotic-resistant bacteria spreading on plastic debris.
New insights on municipal solid waste (MSW) landfill plastisphere structure and function
Characterization of a large municipal solid waste landfill plastisphere found that plastic surfaces harbored more diverse bacterial communities than surrounding refuse, with abundant plastic-degrading genera including Bacillus, Pseudomonas, and Paenibacillus detected in both environments.
Increased inheritance of structure and function of bacterial communities and pathogen propagation in plastisphere along a river with increasing antibiotics pollution gradient.
This study examined how bacterial communities colonizing plastic debris in a river — the Plastisphere — change along a gradient of increasing antibiotic pollution. Plastic debris hosted distinct microbial communities compared to surrounding water, and areas with higher antibiotic levels showed greater inheritance of resistant bacterial structures on plastic surfaces, suggesting plastics facilitate the spread of antibiotic resistance.
Plastisphere as a Vector for Pathogenic Microbes and Antibiotic Resistance
This review examines how the plastisphere, the microbial community that colonizes plastic surfaces, serves as a vector for pathogenic bacteria and antibiotic resistance genes. Researchers found that microplastics can adsorb antibiotics and facilitate higher rates of plasmid transfer among bacteria, with potentially pathogenic species carrying multi-drug resistance genes identified on plastic surfaces.
Microplastics act as vectors for antibiotic resistance genes in landfill leachate: The enhanced roles of the long-term aging process
This study examined whether the aging of microplastics in aquatic environments influences their role as vectors for antibiotic resistance genes (ARGs). Aged microplastics showed different ARG enrichment patterns on their surfaces compared to pristine particles, suggesting that weathering changes the capacity of plastic debris to accumulate and spread antibiotic resistance.
Microplastics as carriers of antibiotic resistance genes and pathogens in municipal solid waste (MSW) landfill leachate and soil: a review
This review examines how microplastics in landfill leachate and soil can serve as carriers for antibiotic resistance genes and disease-causing bacteria. Researchers describe how microplastic surfaces create favorable environments for bacterial colonization and gene transfer, potentially spreading antimicrobial resistance. The study highlights an underappreciated pathway through which plastic waste in landfills may contribute to the broader antibiotic resistance crisis.
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.
The plastisphere ecology: Assessing the impact of different pollution sources on microbial community composition, function and assembly in aquatic ecosystems
Researchers studied the microbial communities living on microplastic surfaces (called the plastisphere) across four different aquatic sites and found that plastics host a distinctly different mix of microbes than the surrounding water, shaped by local pollution sources. These plastic-surface microbes also carry more antibiotic resistance genes and show greater potential for breaking down plastics, making the plastisphere both a health concern and a potential bioremediation resource.
Microplastisphere antibiotic resistance genes: A bird's-eye view on the plastic-specific diversity and enrichment
Microplastics in the environment act as surfaces for microbial communities called microplastispheres, which this review finds are enriched with antibiotic resistance genes (ARGs). The type of plastic, surrounding water chemistry, and co-occurring pollutants all influence which resistance genes accumulate, raising concern that microplastics could be spreading antibiotic resistance through aquatic environments worldwide.
Sources, 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.
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.

A roadmap for a Plastisphere
This paper discusses the concept of the 'Plastisphere'—the total surface area of plastic debris in the environment that hosts unique microbial communities. The author reviews current knowledge and outlines a research roadmap for understanding how the Plastisphere affects ecosystem function and potentially human health through the spread of pathogens and antibiotic resistance.
Associations between bacterial communities and microplastics from surface seawater of the Northern Patagonian area of Chile
Researchers characterized bacterial communities on microplastics collected from three coastal sites with varying aquaculture activity in Chilean Patagonia, identifying 3,102 OTUs dominated by Cyanobacteria, Bacteroidetes, and Proteobacteria, with communities differing from surrounding seawater at all sites. Despite site-specific variation, 222 bacterial OTUs were shared across all three locations, suggesting a core plastisphere community that persists across different anthropogenic conditions.
From rivers to marine environments: A constantly evolving microbial community within the plastisphere
Researchers sampled 107 plastic pieces across four aquatic ecosystems in southern France and found that the sampling location and polymer chemistry were the strongest drivers of plastisphere microbial community composition, while only 11% of samples showed elevated Vibrio pathogen levels compared to surrounding water.
