ClearBacterial community structure of water, sediment and microplastics in Poyang Lake wetland.
This study compared the bacterial communities living on four types of microplastics (film, foam, fiber, and fragment) in Poyang Lake wetland in China against the bacterial communities in the surrounding water and sediment. The microplastic surfaces hosted distinct microbial communities that differed from both the water and sediment, with foam microplastics supporting the least diverse communities. This "plastisphere" research is important because the unique bacteria colonizing plastic surfaces could spread pathogens or alter nutrient cycles in freshwater wetland ecosystems.
[Characterization of Microplastic Surface Bacterial Community Structure and Prediction of Ecological Risk in Poyang Lake, China].
Researchers characterized bacterial communities on microplastic surfaces (PE, PET, PP, PS) in Poyang Lake using 16S high-throughput sequencing, finding that microplastic surfaces harbored distinct communities with lower diversity than surrounding water and sediment, dominated by Proteobacteria and Bacteroidota with Massilia and Pseudomonas as key genera.
Effects of microplastics on bacterial communities in lake wetland sediments: a comparison between drought and flooded conditions
Researchers established a sediment microcosm system for Poyang Lake wetland and examined the effects of polyethylene and polypropylene microplastics on bacterial community structure, functional genes, and ecological processes over 180 days under both simulated drought and flooded conditions.
Comparative analysis of microplastic and microbial communities in varied aquatic environments: Disparities in occurrence, interconnections, and ecological implications
Comparative surveys of microplastics and associated microbial communities across river, reservoir, and bay environments in the Dongjiang watershed found that MP abundance and microbial community composition differed significantly by water type, with MP surfaces hosting distinct microbial assemblages.
Uniqueness and Dependence of Bacterial Communities on Microplastics: Comparison with Water, Sediment, and Soil
Researchers compared bacterial communities on microplastics with those in water, sediment, and soil in the Three Gorges Reservoir area, finding that microplastic-associated communities are unique in composition and ecological function compared to surrounding environments.
Substrate-driven microbial diversity and functional potential of plastisphere biofilms in a dynamic coastal ecosystem of northeastern Taiwan
Researchers used full-length 16S rRNA sequencing to compare microbial communities on floating microplastics, natural wood debris, and surface seawater from ten coastal sites in Taiwan, finding that microplastics harbor unique and highly diverse microbial assemblages distinct from those on natural surfaces.
Distinct microbial communities in the microplastisphere of inland wetlands: Diversity, composition, co-occurrence networks, and functions.
Researchers collected samples from different inland wetland types to characterize the microbial communities colonizing plastic surfaces (the microplastisphere), finding distinct bacterial and fungal communities compared to surrounding soils. Community composition varied by wetland type and plastic surface, highlighting the ecological diversity of plastic-associated microbiomes in freshwater habitats.
Microplastic-associated bacterial assemblages in the intertidal zone of the Yangtze Estuary
Researchers used high-throughput DNA sequencing to profile bacterial communities colonizing microplastics in the intertidal zone of China's Yangtze Estuary, finding that plastisphere community composition reflected the particles' sedimentary versus aquatic origins and included keystone taxa adapted to surface-colonization as well as potential pathogens hitchhiking on plastic surfaces.
Characteristics of microplastic pollution and analysis of colonized-microbiota in a freshwater aquaculture system.
Researchers found microplastics averaging 288.53 items per liter in freshwater aquaculture ponds in China, dominated by transparent fibers and cellulose particles, and discovered that bacterial communities on microplastic surfaces had significantly higher species richness and diversity than those in surrounding water. The plastisphere communities were enriched with Proteobacteria, including cellulose-degrading and potentially pathogenic species.
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.
Biofilms in plastisphere from freshwater wetlands: Biofilm formation, bacterial community assembly, and biogeochemical cycles
Researchers studied how bacteria form biofilms on microplastic surfaces in freshwater wetlands and found that these plastic-associated communities differ significantly from natural soil bacteria. The microplastic biofilms had lower diversity but higher activity in carbon processing and nitrogen cycling genes. This means microplastics in wetlands can alter natural nutrient cycles, potentially affecting water quality in ecosystems that many communities rely on.
Colonization Characteristics of Bacterial Communities on Plastic Debris Influenced by Environmental Factors and Polymer Types in the Haihe Estuary of Bohai Bay, China
Bacterial communities colonizing plastic debris in the Haihe Estuary of Bohai Bay, China, were shaped by both environmental factors (season, salinity, temperature) and the type of plastic polymer, with distinct microbial assemblages forming on different plastic surfaces. The results demonstrate that the "plastisphere" in estuarine environments is a dynamically structured microbial habitat.
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.
Edaphic Gradients Reshape Microbial Microenclaves Assembly within Plastispheres
Researchers sampled microplastics and surrounding soils at 27 urban wetland sites in China to study how bacteria colonize plastic surfaces, forming communities known as plastispheres. They found that plastispheres selectively recruit soil bacteria but harbor only 52-69% of the bacterial diversity found in adjacent soil. The study reveals that soil nutrient levels and moisture conditions strongly influence how these microplastic-associated microbial communities assemble.
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.
Colonization characteristics of bacterial communities on microplastics compared with ambient environments (water and sediment) in Haihe Estuary
Bacterial communities colonizing microplastics in Haihe Estuary sediments and water were found to differ substantially from ambient environmental communities, with microplastics selecting for distinct bacterial assemblages including potential pathogens. This confirms that microplastics create ecological niches that alter microbial ecology in estuarine environments.

Researchers characterized prokaryotic and eukaryotic plastisphere communities on microplastics from four lakes in Italy using 16S and 18S rRNA high-throughput sequencing and fluorescence in situ hybridization with confocal laser scanning microscopy. Despite geographic variation among sites, plastisphere communities shared a core microbiome of known biofilm formers that was compositionally distinct from surrounding planktonic communities.
Characterizing Microplastic Pollution and Microbial Community Status in Rice Paddy Soils Across Varied Environmental Settings in Songjiang, Shanghai: An Analysis of Morpho-Chemical Characteristics

Plastic-associated microbial communities differed from bulk soil communities, suggesting microplastics create distinct microbial niches in agricultural environments.
