ClearEvidence 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.
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.
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.
Formation of specific bacterial assemblages on sterile polyethylene microplastic particles added to a marine aquaria system
Researchers characterized bacterial assemblages that formed on sterile polyethylene microplastic particles after 12 weeks of incubation in marine aquaria, comparing the plastisphere communities to those on sterile sandy sediment and in water fractions to determine whether microplastics select for distinct or potentially pathogenic bacterial communities. The study found that microplastics hosted specific bacterial assemblages distinct from surrounding environmental fractions, confirming their role as selective surfaces for microbial colonization.
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.
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.

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.
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.
Environmental Factors Support the Formation of Specific Bacterial Assemblages on Microplastics
Researchers incubated polystyrene, polyethylene, and wooden pellets across marine and freshwater environments and found that environmental conditions — more than plastic type — drove the formation of specific bacterial communities on microplastics, with plastic-specific assemblages only emerging under certain conditions.
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.

Researchers investigated how microbial biofilm communities on marine plastics vary by season, location, and plastic type in Northern European waters. The study found distinct spatial and seasonal patterns in plastisphere microbial communities on polyethylene terephthalate surfaces, providing insights into how plastic debris develops unique biological communities in marine environments.
Are bacterial communities associated with microplastics influenced by marine habitats?
A three-month field exposure experiment on a Chinese island compared bacterial communities on polyethylene and PET microplastics in three marine habitats (intertidal, supralittoral, seawater), finding that habitat significantly shaped community structure but polymer type had a weaker influence.

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.

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.

This study provided direct experimental evidence that microplastic surfaces selectively enrich bacteria capable of degrading plastic polymers, addressing the long-standing hypothesis that the plastisphere harbors plastic-degrading microbes. Bacteria isolated from microplastic biofilms demonstrably used plastic as a carbon source, confirming that environmental microplastics actively select for and concentrate plastic-degrading communities.
