Microplastics as a New Ecological Niche For Multispecies Microbial Biofilms within the Plastisphere
This review examines microplastics as a novel ecological niche — the 'plastisphere' — analyzing how multispecies microbial biofilms colonize plastic surfaces, differ from surrounding environmental communities, and may facilitate biodegradation and horizontal gene transfer.
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.
Microplastic aging and plastisphere succession in mangrove sediments: Mechanisms, microbial interactions, and degradation potential
Microplastic aging processes and the succession of microbial communities (plastisphere) in mangrove sediments were tracked over time, revealing how the plastic surface microbiome changes as particles weather.

Researchers studied how microplastics affect nitrogen-cycling microbial communities in mangrove ecosystems under varying salinity and tidal conditions. They found that microplastic surfaces hosted distinct microbial communities with significantly higher abundances of nitrogen-cycling genes compared to surrounding soils. The study suggests that microplastics may act as hotspots for nitrogen transformation in mangrove environments, potentially disrupting natural nutrient cycling.
Insights into co-occurrence characteristics and interplay of microbial communities and environmental pollutants on biofilm-colonized microplastics in mangrove ecosystems
Researchers conducted an in situ study in mangrove ecosystems examining how microplastics accumulate biofilms over time, finding progressive development of microbial communities across seasons, polymer types, and exposure durations, with heavy metals and persistent organic pollutants co-occurring on microplastic surfaces.
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.
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.
Profiles of bacterial assemblages from microplastics of tropical coastal environments
Microplastic pieces collected from tropical coastal environments in Malaysia were found to host distinct bacterial communities that differed from surrounding seawater, including potential pathogens and plastic-degrading bacteria. The study contributes to understanding the plastisphere in tropical regions, where warm temperatures may accelerate both microbial colonization and plastic degradation.
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.
Rhizospheric bacterial communities against microplastics (MPs): Novel ecological strategies based on the niche differentiation
Researchers studied how bacterial communities living around plant roots adapt when exposed to microplastics in soil. They found that rhizosphere bacteria developed distinct survival strategies depending on their ecological niche, with some species thriving while others declined in the presence of plastics. The study reveals that microplastics can reshape the microbial communities that plants depend on for nutrient uptake and disease resistance.

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.
Investigating the roles of microbes in biodegrading or colonizing microplastic surfaces
Researchers investigated the roles of microbes in biodegrading or colonizing microplastic surfaces, examining how microbial communities interact with plastic polymers in environmental settings.

The ecology of the plastisphere: Microbial composition, function, assembly, and network in the freshwater and seawater ecosystems
Researchers studied the communities of bacteria and fungi that colonize microplastic surfaces in freshwater and seawater, forming what scientists call the plastisphere. These microplastic-associated communities were distinctly different from those in surrounding water, and included a higher proportion of disease-causing organisms and species involved in pollutant degradation. The findings suggest that microplastics create new habitats that can harbor pathogens and alter natural microbial ecosystems in ways that may affect water quality and human health.
