ClearMicroplastic bacterial communities in the Bay of Brest: Influence of polymer type and size
Researchers analyzed bacterial communities growing on microplastics collected from a coastal bay in France and found that the type of polymer influenced which bacteria colonized the surface. Different plastics like polyethylene, polypropylene, and polystyrene each hosted distinct microbial communities, though particle size had less influence. The study reveals that microplastics in the ocean serve as unique habitats for bacteria, which could have implications for how pollutants and pathogens are transported through marine environments.
Environmental exposure more than plastic composition shapes marine microplastic‐associated bacterial communities in Pacific versus Caribbean field incubations
Researchers incubated six types of household plastic polymers in Pacific and Caribbean coastal waters to study the bacterial communities that form on microplastics. They found that geographic location and exposure time were far more important than plastic type in shaping these microbial communities. The study identified a core plastisphere of 57 bacterial variants common across all conditions, suggesting environmental context plays a bigger role than plastic composition in microplastic colonization.
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.
The structure and assembly mechanisms of plastisphere microbial community in natural marine environment
Researchers investigated how microbial communities colonize different types of microplastic surfaces in natural marine environments over an eight-week period. They found that the composition of these plastic-associated microbial communities, known as the plastisphere, was shaped more by environmental conditions and time than by the specific type of plastic. The study provides new understanding of the ecological processes governing how microorganisms assemble on ocean plastic debris.
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.
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.
Microbial colonization of microplastics in the Caribbean Sea
Researchers incubated six common plastic polymers in Caribbean waters for six weeks and found that bacterial biofilm communities were not significantly shaped by plastic type or exposure time, but eukaryotic communities (including distinctive diatom assemblages) were influenced by both factors. This suggests that microplastics act as selective habitats for some microbial groups but not others, with implications for understanding how plastics alter ocean microbial ecology.
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.
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.
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.

Researchers studied bacterial communities colonizing plastic bottles in marine environments, finding that substrate type, season, and geographic location all influenced which microbes colonized the plastic surface.
Colonization characteristics of bacterial communities on plastic debris: The localization of immigrant bacterial communities
Researchers investigated the colonization characteristics of bacterial communities on plastic debris in environmental settings, finding that the localization of immigrant bacterial communities on plastic surfaces reflects specific colonization dynamics distinct from random sampling effects.
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.
Niche vs. habitat: Insights of aging microplastics and wetland types on bacterial community assembly
Researchers studied how bacterial communities assemble on microplastic surfaces (plastispheres) versus surrounding soil in three types of wetlands using low-density polyethylene. They found that wetland habitat type had a stronger influence on bacterial diversity patterns than whether the plastic was virgin or aged, with plastisphere communities showing lower diversity and more stochastic assembly compared to soil 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.
Deciphering the Mechanisms Shaping the Plastisphere Microbiota in Soil
Researchers characterized bacterial communities colonizing biodegradable and conventional microplastics in soil, finding that polymer type and biodegradability shaped distinct plastisphere communities, with deterministic processes playing a stronger role in community assembly than in surrounding soil.
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.
Uniqueness and Dependence of Bacterial Communities on Microplastics: Comparison with Water, Sediment, and Soil

Time-series incubations in a coastal environment illuminates the importance of early colonizers and the complexity of bacterial biofilm dynamics on marine plastics
Researchers used time-series incubations in a coastal marine environment to track plastisphere biofilm formation on microplastics, finding that early bacterial colonizers play a disproportionate role in shaping community dynamics and that biofilm composition is highly complex, varying with polymer type, incubation time, and surrounding environment.
Differentiation of bacterial communities on five common plastics after six days of exposure to Caribbean coastal waters
Researchers found that within just six days of entering Caribbean coastal waters, different plastic polymers — including polystyrene, polyethylene, and nylon — develop distinct microbial communities on their surfaces, with plastic-degrading bacteria rapidly increasing in abundance. This "plastisphere" research shows that the type of plastic influences which microbes colonize it, which could affect both plastic breakdown rates and the spread of microbes in ocean environments.
