ClearMicroplastic 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.
Ecological 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.
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.
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.
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.
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 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.
Impact de la pollution plastique sur les communautés microbiennes de rivière
This study investigates how plastic pollution affects microbial communities in rivers, focusing on the 'plastisphere' — the distinct biofilm communities that form on plastic surfaces in aquatic environments. Plastics not only carry unique microbial assemblages but may also harbor potentially harmful microorganisms, raising concerns for aquatic ecosystem health.
Plastisphere as a unique metabolic hotspot in river water: Impact of plastic substrate biodegradability
A study of river water found that microplastic surfaces — even from tiny 100-micrometer particles — host distinct microbial communities called plastispheres that function as metabolic hotspots, with richer carbon and nitrogen cycling activity than the surrounding water. The biodegradability of the plastic substrate influenced which microbes colonized it and how they interacted, with biodegradable plastics supporting different communities than conventional plastics. This matters because plastisphere microbes can include potential pathogens and antibiotic-resistant bacteria, and they alter the ecological function of freshwater environments.
Uniqueness and Dependence of Bacterial Communities on Microplastics: Comparison with Water, Sediment, and Soil
Researchers compared bacterial communities on microplastics with those in water, sediment, and soil in the Three Gorges Reservoir area, finding that microplastic-associated communities are unique in composition and ecological function compared to surrounding 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.

Researchers investigated plastic-associated bacterial communities on microplastic surfaces in a Hungarian freshwater lake, finding that the plastisphere harbored distinct microbial communities compared to surrounding water, including potential pathogens and plastic-degrading bacteria.
Microbial community niches on microplastics and prioritized environmental factors under various urban riverine conditions
Researchers manipulated organic content, salinity, and dissolved oxygen in bioreactors to assess which environmental factors most strongly shaped microbial communities colonizing microplastics in urban rivers. Dissolved oxygen and organic carbon content were identified as priority drivers of plastisphere community composition, with implications for predicting pathogen enrichment on MPs across river conditions.
Longitudinal patterns of microplastic concentration and bacterial assemblages in surface and benthic habitats of an urban river
This study measured microplastic concentrations and microbial communities in a river from source to mouth, finding that both plastic levels and unique plastisphere bacterial communities increased downstream of wastewater treatment plant outflows. The results identify wastewater discharge as a key driver of both microplastic loading and microbial community shifts in rivers.
Stronger Geographic Limitations Shape a Rapid Turnover and Potentially Highly Connected Network of Core Bacteria on Microplastics
Core bacterial communities on microplastics were investigated across river ecosystems, revealing that geographic factors strongly limited microbial sharing between sites and that plastic-associated microbiota turned over rapidly along river gradients. The findings suggest that microplastics in rivers carry largely location-specific bacterial assemblages rather than universally dispersed communities.
Viral diversity and potential environmental risk in microplastic at watershed scale: Evidence from metagenomic analysis of plastisphere
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.
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.
Survival of human pathogens bound to microplastics during transfer through the freshwater-marine continuum: from wastewater discharge to the beach
Researchers tracked survival of E. coli, E. faecalis, and P. aeruginosa colonizing polyethylene microplastics as particles were transferred through a series of mesocosms simulating downstream transport from wastewater effluent through freshwater, estuary, seawater, and beach sand. All three pathogens survived the full environmental transition sequence in the plastisphere, with higher bacterial concentrations on microplastics than on glass controls, though die-off rates did not differ by substrate, demonstrating microplastics' potential to extend pathogen persistence across environmental boundaries.
Microplastics accumulate priority antibiotic-resistant pathogens: Evidence from the riverine plastisphere
Researchers placed microplastics in river water and found they accumulated more antibiotic-resistant bacteria than natural sand particles, including dangerous pathogens like E. coli and Klebsiella. Most of the bacteria isolated from the plastic surfaces were multi-drug resistant and carried virulence traits like biofilm formation. This suggests microplastics in waterways may act as rafts for spreading antibiotic resistance through the environment.
Microplastic in surface waters of urban rivers: concentration, sources, and associated bacterial assemblages
Researchers measured microplastic levels in the surface waters of the Chicago River and its urban tributaries, finding concentrations as high as 1.94 particles per cubic meter near wastewater outflows. They discovered that microplastic fibers and pellets were often colonized by bacterial communities distinct from those in the surrounding water. The study provides early evidence that urban rivers are significant conduits for microplastic pollution and that these particles may serve as rafts for microorganisms.

Evidence for selective bacterial community structuring on microplastics
Plastic substrates incubated in Baltic Sea water developed distinct bacterial communities that differed significantly from those on glass surfaces and from the surrounding water, with some plastic-colonizing taxa selected for regardless of polymer type. The study provides experimental evidence that plastic surfaces act as selective filters for microbial community assembly, contributing to the concept of a unique plastisphere.
