ClearLacustrine 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.
Microbial colonizers of microplastics in an Arctic freshwater lake
Researchers characterized the microbial communities that colonize biodegradable and non-biodegradable microplastics deployed in an Arctic freshwater lake over eleven days. The study found that the plastisphere microbial community was complex and differed from the surrounding water, with biodegradable plastic attracting distinct bacterial groups, suggesting that microplastic type influences which microorganisms colonize these particles in pristine environments.
Microplastic surface properties affect bacterial colonization in freshwater
Researchers incubated six types of microplastics in Lake Erie water for eight weeks and found that bacterial colonization patterns differed significantly depending on plastic surface properties such as roughness, hydrophobicity, and weathering. The study suggests that eroded microplastics, which better mimic environmental conditions, are colonized differently than pristine particles, which has implications for how plastics transport bacteria in freshwater ecosystems.
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.
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.
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.
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.
In Situ Investigation of Plastic-Associated Bacterial Communities in a Freshwater Lake of Hungary
Researchers investigated plastic-associated bacterial communities on microplastic surfaces in a Hungarian freshwater lake, finding that the plastisphere harbored distinct microbial communities compared to surrounding water, including potential pathogens and plastic-degrading bacteria.
Effects of microplastics on the structure and function of bacterial communities in sediments of a freshwater lake
Researchers examined how microplastics alter the structure and function of bacterial communities in sediments, finding that plastic exposure shifted community composition and reduced overall diversity compared to plastic-free controls. Functional analysis showed impaired denitrification and organic matter decomposition in microplastic-contaminated sediments, indicating ecosystem-level consequences for nutrient cycling.
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.
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.
Changes in microplastic-associated bacterial communities along a salinity gradient in Central Anatolian lakes of Türkiye
Researchers examined bacterial communities growing on microplastic surfaces across 11 Turkish lakes spanning a wide range of salinity levels. They found that Pseudomonadaceae bacteria dominated the microplastic biofilms, and several salt-tolerant pathogenic species were detected on plastic surfaces even in highly saline lakes. The study highlights that microplastics can serve as vehicles for potentially harmful bacteria across diverse freshwater environments.

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.
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.
No trophy for the trophy? - How lake trophy impacts bacterial assemblages of biofilm on microplastic
A field experiment incubating microplastics in five lakes with different nutrient levels (trophy) found that bacterial biofilm composition on MPs was dominated by Proteobacteria and differed significantly from free-water communities, but lake trophy had limited influence on overall biofilm diversity. This suggests that plastic surfaces create a distinct microbial niche independent of the surrounding water quality, with implications for how plastic-associated bacteria spread through freshwater ecosystems.
Microbial Dynamics on Different Microplastics in Coastal Urban Aquatic Ecosystems: The Critical Roles of Extracellular Polymeric Substances
Researchers investigated how microbial communities colonize different types of microplastics in urban coastal waters, forming distinct ecosystems known as plastispheres. They found that the type of plastic significantly shaped which bacteria grew on it and how much sticky extracellular material they produced. Understanding these microbial communities on microplastics matters because they can harbor harmful bacteria and influence how pollutants move through aquatic environments.

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.
Microbiomes on microplastics versus natural microcarriers: Stability and transformation during aquatic travel from aquaculture ponds to adjacent stream
Researchers compared microbial communities that form on microplastics versus natural materials as they travel from aquaculture ponds to adjacent streams. They found that different plastic types harbored distinct microbial communities, and that these plastisphere communities were less stable than those on natural substrates during transit between water bodies. The study suggests that microplastics may spread different assemblages of microorganisms as they move through connected aquatic environments.
