ClearEcological Roles and Shared Microbes Differentiate the Plastisphere from Natural Particle-Associated Microbiomes in Urban Rivers
Researchers compared the microbial communities living on microplastics versus natural particles in ten urban river systems. While the two communities shared many similarities, the microplastic-associated community, known as the plastisphere, harbored distinct bacteria with specialized abilities to break down complex carbon compounds. The study suggests that microplastics in rivers create unique microbial habitats that may influence nutrient cycling and pollutant degradation differently than natural particles.
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.
The ecology of the plastisphere: Microbial composition, function, assembly, and network in the freshwater and seawater ecosystems
Researchers studied the communities of bacteria and fungi that colonize microplastic surfaces in freshwater and seawater, forming what scientists call the plastisphere. These microplastic-associated communities were distinctly different from those in surrounding water, and included a higher proportion of disease-causing organisms and species involved in pollutant degradation. The findings suggest that microplastics create new habitats that can harbor pathogens and alter natural microbial ecosystems in ways that may affect water quality and human health.
Plastisphere in freshwaters: An emerging concern
This review introduced the concept of the freshwater plastisphere - the microbial community colonizing plastic debris in rivers and lakes - and found that freshwater plastisphere communities are compositionally distinct from marine ones and from ambient water microbiomes, with implications for pathogen dispersal and plastic degradation in inland waters.
Ecological Rolesand Shared Microbes Differentiatethe Plastisphere from Natural Particle-Associated Microbiomes in UrbanRivers
Researchers compared the microbiomes on microplastics (the 'plastisphere') versus natural particles in ten urban rivers using metagenomics, finding similar overall taxonomic and functional compositions between the two. However, the plastisphere harbored distinct specialist taxa with enhanced capacity for complex carbohydrate metabolism and unique ecological strategies.
Plastic substrate and residual time of microplastics in the urban river shape the composition and structure of bacterial communities in plastisphere
Researchers conducted an in-site incubation experiment in an urban river using microplastics from three plastic product types (garbage bags, shopping bags, and plastic bottles), finding that both plastic substrate type and incubation time shaped the bacterial communities colonizing the plastisphere. Different plastic products harbored distinct microbial communities, with potential implications for the spread of plastic-associated microorganisms in urban freshwater.
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.
Freshwater plastisphere: a review on biodiversity, risks, and biodegradation potential with implications for the aquatic ecosystem health
This review examines the communities of microbes that colonize plastic debris in freshwater environments, known as the "plastisphere." These microbial communities include potentially dangerous bacteria and organisms that can carry antibiotic resistance genes, meaning plastic pollution may serve as a vehicle for spreading pathogens and drug-resistant infections through water systems that people rely on.
Microplastic is an Abundant and Distinct Microbial Habitat in an Urban River
Researchers demonstrated that microplastic surfaces in an urban river host a microbial community that is distinct from surrounding water and sediment communities, establishing microplastic as an abundant and ecologically distinct habitat for river microorganisms.
Aquatic Microbial Diversity on Plastisphere: Colonization and Potential Role in Microplastic Biodegradation
This review examines how microorganisms colonize the surfaces of floating plastic debris in aquatic environments, forming communities known as the plastisphere. Researchers found that certain bacteria and fungi on plastic surfaces show potential for biodegrading the polymers they inhabit. The study suggests that understanding these microbial communities could lead to biological approaches for breaking down microplastic pollution in waterways.
Microplastics: New substrates for heterotrophic activity contribute to altering organic matter cycles in aquatic ecosystems
This study demonstrated that heterotrophic bacteria colonizing microplastic surfaces in aquatic ecosystems have distinct metabolic capabilities and can process organic matter at rates different from planktonic bacteria. The findings suggest that the plastisphere — the microbial community on plastic surfaces — may alter organic matter cycling in aquatic environments as microplastic abundance grows.
Ecological Rolesand Shared Microbes Differentiatethe Plastisphere from Natural Particle-Associated Microbiomes in UrbanRivers
This metagenomics study across ten urban rivers confirmed that the plastisphere shares broad taxonomic and functional similarities with microbiomes on natural particles, but exhibits unique ecological roles through specialist taxa. These differences may amplify the plastisphere's capacity for nutrient cycling and potentially harbor pathogens or antibiotic resistance genes.

The review synthesizes information on Plastisphere formation mechanisms, distribution in water, risks associated with pathogen and pollutant transport, and potential applications for removing microplastics from contaminated water.
Distinctive patterns of bacterial community succession in the riverine micro-plastisphere in view of biofilm development and ecological niches
Scientists studied how bacterial communities develop on microplastics versus natural materials in river water and found that plastics support a distinct pattern of microbial colonization. The research identified specific bacteria capable of degrading microplastics and revealed that competition among microbes on plastic surfaces follows unexpected patterns compared to natural substrates.
Plastisphere Community Assemblage in Freshwater
This review synthesizes research on plastisphere communities in freshwater environments, where micro-, nano-, and macroplastic particles serve as artificial microhabitats for microbial colonization. The authors found that freshwater plastisphere communities differ markedly from those on natural substrates and pose elevated risks by harboring pathogens, antibiotic-resistant genes, and toxic pollutants that can enter organisms through plastic ingestion.

Wastewater discharges and polymer type modulate the riverine plastisphere and set the role of microplastics as vectors of pathogens and antibiotic resistance
Researchers investigated how wastewater treatment plant discharges and polymer type shape microbial communities on microplastics in a river environment. They found that microplastics harbored significantly higher microbial diversity than surrounding water, and that wastewater discharges led to a 2.3-fold increase in antibiotic resistance gene abundance on the plastic surfaces. Different polymer types, including polyethylene, polypropylene, and PET, each attracted distinct microbial communities with varying levels of pathogens and resistance genes.
