The Effect of Microplastics on Microbial Succession at Impaired and Unimpaired Sites in a Riverine System

Lacustrine plastisphere: Distinct succession and assembly processes of prokaryotic and eukaryotic communities and role of site, time, and polymer types
Researchers investigated how microbial communities colonize different types of microplastic polymers in freshwater lakes. The study found that bacteria and single-celled organisms follow distinct assembly patterns on microplastic surfaces, with colonization time, location, and polymer type all influencing community composition. These findings suggest microplastics serve as carriers that can promote microbial spread in aquatic environments.
Biofilms on plastic litter in an urban river: Community composition and activity vary by substrate type
Researchers examined biofilms colonizing plastic litter versus natural surfaces in an urban river, finding that community composition and metabolic activity vary by substrate type, with plastic surfaces hosting distinct microbial communities that may influence plastic degradation rates.
Distinct 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.
A domesticated photoautotrophic microbial community as a biofilm model system for analyzing the influence of plastic surfaces on invertebrate grazers in limnic environments
Researchers developed a domesticated photoautotrophic microbial community as a biofilm model system to analyse how plastic surfaces influence invertebrate grazers in freshwater environments. The study found that biofilms growing on plastic substrates affected grazer behaviour and feeding differently than biofilms on natural surfaces, with implications for understanding how plastic pollution disrupts limnic food web interactions.
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.

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.
Unraveling Microplastic-Biofilm Nexus in Aquaculture: Diversity and Functionality of Microbial Communities and Their Effect on Plastic Traits
Researchers incubated five common types of microplastics in an aquaculture pond for 128 days and found that biofilm formation varied significantly depending on the plastic type, with polypropylene and polyethylene supporting the richest microbial communities. PET microplastics attracted more plastic-degrading bacteria like Pseudomonas, while all plastic types enriched potentially pathogenic microorganisms. The findings highlight how different microplastics selectively shape microbial colonization in aquaculture environments, with implications for both environmental health and food safety.
Epiplastic microhabitats for epibenthic organisms: a new inland water frontier for diatoms
Researchers studied how diatoms — microscopic single-celled algae — colonize plastic surfaces floating in a freshwater pond in Italy over nine months. The number of diatom species increased over time on both polystyrene and PET plastics, suggesting that plastic debris in inland waters creates new artificial habitats that could alter freshwater ecosystems.
Long-term study of the bacterial colonization of polypropylene microplastics in a freshwater lake by optical and molecular methods
This long-term study monitored bacterial colonization on polypropylene microplastic surfaces in a freshwater environment over an extended period, tracking how the plastisphere community develops and changes over time. Long-term data on plastisphere development reveals that microplastic surfaces support distinct and evolving microbial communities that differ from surrounding water, potentially harboring pathogenic or antibiotic-resistant bacteria.
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.
Temporal dynamics of bacterial colonization on five types of microplastics in a freshwater lake
Researchers submerged five types of microplastics in a freshwater lake for about a year to study how bacterial communities colonize their surfaces over time. They found that different plastic types attracted distinct microbial communities, which changed significantly across seasons. The study reveals that microplastics serve as unique habitats for bacteria in freshwater, potentially influencing nutrient cycling and ecosystem dynamics.
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.
Dynamics of fouling of plastic waste fragments by microorganisms in the Gulf of Finland
Researchers studied how quickly microorganism communities (biofilms) develop on plastic waste fragments in the Gulf of Finland. The plasticosphere — the microbial community colonizing plastic surfaces — forms rapidly and has distinct characteristics from biofilms on natural materials, with potential ecological implications for how pollutants are transported in the marine environment.

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.

Enumeration of aerobic heterotrophic bacteria in early-stage of biofilm formed on different plastic types
Researchers found that bacteria begin colonising common plastic surfaces — polyethylene, polypropylene, and polystyrene — within hours of water exposure, forming measurable biofilms within three weeks. This matters because plastic debris in aquatic environments quickly becomes a habitat for microbes, potentially transporting pathogens or creating a "plastisphere" that could amplify the ecological risks of microplastic pollution.

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.
