ClearAnalysis of 16S rRNA amplicon data illuminates the major role of environment in determining the marine plastisphere microbial communities
By reanalyzing publicly available microbiome data from marine microplastics collected at multiple ocean locations, this study found that the surrounding water environment shapes the community of microbes living on plastic surfaces (the plastisphere) more strongly than the type of plastic polymer does. While both location and polymer type matter, once environmental differences were accounted for, polymer type alone had no statistically significant effect on microbial diversity. This is important because microplastics can carry and transport harmful microbes across vast ocean distances, and understanding what controls those communities helps assess the ecological risk.
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.
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.
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.
Microbes on a Bottle: Substrate, Season and Geography Influence Community Composition of Microbes Colonizing Marine Plastic Debris
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.
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.
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.
Analysis of 16S rRNA amplicon data illuminates the major role of environment in determining the marine plastisphere microbial communities
Researchers analysed 16S rRNA amplicon data from marine plastisphere communities, finding that environmental factors play the dominant role in determining the microbial communities that colonise microplastic surfaces in marine ecosystems.
Marine microplastic-associated bacterial community succession in response to geography, exposure time, and plastic type in China's coastal seawaters
Researchers used high-throughput gene sequencing to track how microbial communities on polypropylene and polyvinyl chloride microplastics changed over a full year in Chinese coastal waters. They found that the composition of plastic-associated bacterial communities varied significantly across geographic locations and over time, with Alphaproteobacteria being consistently dominant. The study reveals that the plastisphere is a dynamic ecosystem shaped by both environmental conditions and the duration of exposure.
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.
Microplastic 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.
Exploring changes in microplastic-associated bacterial communities with time, location, and polymer type in Liusha Bay, China
Researchers tracked how bacterial communities colonizing different types of microplastics changed over time in an aquaculture bay in China. They found that both exposure duration and plastic type significantly influenced which bacteria grew on the surfaces, with hydrocarbon-degrading species becoming notably abundant. Concerning from a health perspective, the pathogenic bacterium Vibrio was detected on all microplastic samples, suggesting that floating plastics may serve as rafts for disease-causing organisms.
Temporal succession of marine microbes drives plastisphere community convergence in subtropical coastal waters
Scientists tracked how microbial communities develop on four common plastic types submerged in subtropical coastal waters over 42 days. They found that the passage of time was a bigger driver of community composition than the type of plastic, with bacterial communities on different plastics becoming more similar as biofilms matured. However, these plastic-associated communities remained distinct from those floating freely in the water, suggesting plastics create unique microbial habitats in marine environments.
The geographical and seasonal effects on the composition of marine microplastic and its microbial communities: The case study of Israel and Portugal
Researchers compared microplastic-associated microbial communities in marine environments of Israel and Portugal, finding that both geography and season significantly influence the composition of the plastisphere and its associated bacterial species.
Relative Influence of Plastic Debris Size and Shape, Chemical Composition and Phytoplankton-Bacteria Interactions in Driving Seawater Plastisphere Abundance, Diversity and Activity
This study evaluated the relative influence of plastic debris size, shape, chemical composition, and environmental conditions on the microbial communities colonizing ocean plastics (the plastisphere). Results showed that multiple plastic properties and environmental factors jointly shape which microorganisms colonize plastic surfaces in the marine environment.
Microplastic polymer properties as deterministic factors driving terrestrial plastisphere microbiome assembly and succession in the field
Researchers incubated five common microplastic polymer types in landfill soil for 14 months and used 16S rRNA sequencing to characterize the plastisphere communities that assembled on each polymer. Polymer type was a significant deterministic factor in plastisphere microbiome composition, which differed from surrounding soil communities and varied over time.
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.
Short‐term plastisphere colonization dynamics across six plastic types
Researchers studied the short-term colonization dynamics of microbial communities (plastisphere) forming on six plastic polymer types submerged in marine waters in South Australia, finding polymer-type-specific differences in prokaryotic community composition over four weeks.
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.
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.
