ClearDistinct community structure and microbial functions of biofilms colonizing microplastics
Biofilm communities were established on polyethylene, polypropylene, cobblestone, and wood substrates over 21 days under controlled conditions and compared by 16S rRNA sequencing, finding that plastic substrates harbored distinct microbial communities and functional profiles compared to natural materials. The study demonstrates that microplastics in freshwater environments provide a selective niche that enriches for distinct microbial taxa and metabolic functions.
Unique Bacterial Community of the Biofilm on Microplastics in Coastal Water
Researchers compared bacterial communities forming biofilms on steel, silica, and PVC microplastic surfaces in coastal seawater and found that biofilm composition differed by material type. This shows that the type of plastic surface influences which microbial communities colonize it, with implications for how microplastics may spread specific bacteria.
Wastewater treatment alters microbial colonization of microplastics
Analysis of microplastics and their biofilms across raw sewage, effluent, and sludge at two wastewater treatment plants found that >99% of influent MPs were retained in sludge, and that wastewater treatment substantially altered biofilm microbial composition, enriching bioflocculation-associated taxa.
Effect of different size microplastic particles on the construction of algal-bacterial biofilms and microbial communities
Researchers tested how microplastic particles of different sizes affect algal-bacterial biofilms used for sewage treatment. Smaller nanoplastics caused more damage to the biofilm community, reducing algal growth and shifting microbial diversity, while larger microplastics had milder effects. This matters because algal-bacterial systems are a green technology for water treatment, and microplastic contamination could undermine their effectiveness.
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.
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.
Surface-programmed microbiome assembly in phycosphere to microplastics contamination
Researchers studied how algal-bacterial communities assemble on microplastic surfaces and their potential role in degrading these pollutants. They found that microplastics in wastewater environments develop distinct microbial communities on their surfaces, with certain bacteria showing enhanced plastic-degrading enzyme activity when associated with algae. The study suggests that engineered algal-bacterial systems could offer a sustainable biological approach to microplastic remediation.
Microalgae colonization of different microplastic polymers in experimental mesocosms across an environmental gradient
Microalgal colonization of five different microplastic polymer types was monitored in freshwater mesocosms across an environmental gradient, finding that polymer type, surface properties, and environmental conditions all influenced the biomass and community composition of epiplastic microalgal biofilms.
Genomic and proteomic profiles of biofilms on microplastics are decoupled from artificial surface properties
Genomic and proteomic analysis of biofilms on marine microplastics showed that community composition and functional profiles were primarily shaped by environmental conditions rather than the specific surface properties of the plastic substrate.
Substrate-driven microbial diversity and functional potential of plastisphere biofilms in a dynamic coastal ecosystem of northeastern Taiwan
Researchers used full-length 16S rRNA sequencing to compare microbial communities on floating microplastics, natural wood debris, and surface seawater from ten coastal sites in Taiwan, finding that microplastics harbor unique and highly diverse microbial assemblages distinct from those on natural surfaces.

Structural Diversity in Early-Stage Biofilm Formation on Microplastics Depends on Environmental Medium and Polymer Properties
This study examined the early stages of bacterial biofilm formation on different types of plastic surfaces in different environmental media, finding that both the growth medium and the polymer type influenced which microbial communities colonized the plastic. These plastic-associated biofilms (the plastisphere) can make microplastics more appealing to filter-feeding organisms that mistake them for food.
Diversity and succession of microbial communities on typical microplastics in Xincun Bay, a long-term mariculture tropical lagoon
Researchers tracked microbial community succession on polyethylene, polystyrene, and polypropylene microplastics over 60 days in a tropical mariculture lagoon, finding that plastisphere bacterial diversity exceeded that of surrounding seawater and that community structure shifted significantly over time.
Combined environmental pressure induces unique assembly patterns of micro-plastisphere biofilm microbial communities in constructed wetlands
Researchers studied how biofilm communities form on microplastic surfaces within constructed wetlands used for wastewater treatment. They found that environmental stressors like antibiotics and organic matter created unique microbial communities on microplastics that differed from those on natural surfaces. The study suggests that constructed wetlands, while effective at trapping microplastics, may also foster distinct microbial ecosystems on plastic surfaces that warrant further investigation.

The composition of bacterial communities associated with plastic biofilms differs between different polymers and stages of biofilm succession
Researchers tracked bacterial community development on five different plastic types submerged in coastal waters over two months. They found that bacterial community composition varied by both plastic type and stage of colonization, with distinct early and late succession patterns. The study provides evidence that different plastics may host different microbial communities, which has implications for understanding how plastic pollution influences marine microbial ecology.
Plastics select for distinct early colonizing microbial populations with reproducible traits across environmental gradients
Incubation of virgin microplastics across oceanic transects showed early colonization was reproducibly dominated by Alteromonadaceae with enriched genes for adhesion, biofilm formation, and hydrocarbon degradation, while mature plastic biofilms shifted to Rhodobacteraceae with genes for carbohydrate hydrolysis and photosynthesis.
