ClearThe Effect of Microplastics on Microbial Succession at Impaired and Unimpaired Sites in a Riverine System
Researchers compared microbial biofilm diversity on microplastic polymers and natural substrates at impaired and unimpaired riverine sites, examining how environmental nutrient loads, seasonality, and geography influence microbiome succession on plastic surfaces in freshwater ecosystems.
Microplastic biofilm in fresh- and wastewater as a function of microparticle type and size class
Researchers compared the biofilm communities that form on microplastics of different types and sizes in both freshwater and wastewater, finding that biofilm composition was influenced by particle type, size, and water source. These findings advance understanding of the plastisphere — the microbial community unique to plastic surfaces — and its potential role in spreading microorganism-associated risks.
Comparative analysis of microplastic and microbial communities in varied aquatic environments: Disparities in occurrence, interconnections, and ecological implications
Comparative surveys of microplastics and associated microbial communities across river, reservoir, and bay environments in the Dongjiang watershed found that MP abundance and microbial community composition differed significantly by water type, with MP surfaces hosting distinct microbial assemblages.
Microbiomes on microplastics versus natural microcarriers: Stability and transformation during aquatic travel from aquaculture ponds to adjacent stream
Researchers compared microbial communities that form on microplastics versus natural materials as they travel from aquaculture ponds to adjacent streams. They found that different plastic types harbored distinct microbial communities, and that these plastisphere communities were less stable than those on natural substrates during transit between water bodies. The study suggests that microplastics may spread different assemblages of microorganisms as they move through connected aquatic environments.
Impacts of Pharmaceuticals on Microbial Colonization of Microplastic in Streams
This study examined how pharmaceutical contaminants in streams affect microbial communities that colonize microplastics. Pharmaceutical-exposed microplastics developed distinctly different microbial communities than unexposed ones, suggesting that the combined presence of microplastics and pharmaceuticals creates novel ecological conditions in urban waterways.
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.
Bacterial and fungal assemblages and functions associated with biofilms differ between diverse types of plastic debris in a freshwater system
Researchers characterised bacterial and fungal assemblages on three types of plastic debris in a freshwater urban river system, finding that microbial communities on plastics differ from those in surrounding water. High-throughput sequencing revealed that alpha diversity of bacterial communities was higher on polyethylene microplastics than on other plastic types, with intraspecies interactions between bacteria and fungi differing across diverse plastic substrates.
Partitioning Of Hydrophobic Organic Contaminants And Microbial Communities On Microplastics
This study examined how hydrophobic organic contaminants and microbial communities partition onto microplastics in aquatic environments. Microplastics were found to concentrate toxic chemicals and harbor distinct microbial communities compared to surrounding water, reinforcing their role as vectors for pollutants.
Nascently generated microplastics in freshwater stream are colonized by bacterial communities from stream and riparian sources
Researchers examined bacterial colonization of different types of nascently generated microplastics through time in a freshwater stream ecosystem, finding that colonizing taxa and their degradative abilities varied based on microplastic polymer type and time of exposure.
Microplastic-Associated Biofilms: A Comparison of Freshwater and Marine Environments
This review compared microplastic-associated biofilm communities in freshwater and marine environments, examining how plastic type, ecosystem, and environmental conditions shape the microbial communities that colonize plastic surfaces. Understanding these "plastisphere" communities is important because they may include pathogens and can affect the fate and transport of plastic particles.
Wastewater-induced microplastic biofouling in freshwater: role of particle size and flow velocity
This study examined how wastewater discharge promotes biofouling — the colonization of microplastics by microorganisms — in freshwater environments, finding that particle size and wastewater-derived nutrients both influenced biofilm formation rates and community composition. Wastewater-exposed microplastics rapidly developed distinct microbial communities.
Comparative Analysis of Selective Bacterial Colonization by Polyethylene and Polyethylene Terephthalate Microplastics
Biofilm communities were compared on polyethylene and polyethylene terephthalate microplastics incubated in two freshwater bacterial communities, finding that the original water source bacteria largely determined biofilm composition rather than the plastic type. The study suggests that the plastisphere in freshwater systems reflects local microbial pools more than plastic-specific selection.
Evaluation of prokaryotic and eukaryotic microbial communities on microplastic‐associated biofilms in marine and freshwater environments
Researchers analyzed microbial biofilm communities on microplastic surfaces in both marine and freshwater environments, finding that plastic-associated biofilms harbor distinct prokaryotic and eukaryotic communities with potential roles in plastic biodegradation.
No trophy for the trophy? - How lake trophy impacts bacterial assemblages of biofilm on microplastic
A field experiment incubating microplastics in five lakes with different nutrient levels (trophy) found that bacterial biofilm composition on MPs was dominated by Proteobacteria and differed significantly from free-water communities, but lake trophy had limited influence on overall biofilm diversity. This suggests that plastic surfaces create a distinct microbial niche independent of the surrounding water quality, with implications for how plastic-associated bacteria spread through freshwater ecosystems.
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.
Microbiological perspectives on the effects of microplastics on the aquatic environment
This review examines how microplastics interact with microorganisms in aquatic environments, highlighting risks to microbial communities and the potential for microplastics to disrupt ecosystem functions. Microplastics may alter microbial diversity and promote the spread of antibiotic-resistant bacteria.

Researchers investigated biofilm formation on low-density polyethylene microparticles in lake water microcosms, finding that microplastic surfaces supported distinct and dynamic microbial communities that differed from those in the surrounding water.
Diversity and structure of microbial biofilms on microplastics in riverine waters of the Pearl River Delta, China
Microbial biofilm communities on microplastics in Pearl River Delta waterways showed distinct composition and diversity compared to surrounding water and natural surfaces, with river environmental conditions more influential than plastic polymer type in shaping biofilm structure.
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.
Evidence of selective enrichment of bacterial assemblages and antibiotic resistant genes by microplastics in urban rivers
Researchers sampled microplastics from two urban rivers in China and found that the bacterial communities colonizing plastic particles were distinctly different from those in the surrounding water. The microplastic-associated bacteria had lower diversity but higher proportions of biofilm-forming species and functions linked to human disease. Notably, the study found that microplastics selectively enriched antibiotic resistance genes, raising concerns about plastics serving as reservoirs for drug-resistant bacteria.
