ClearMicroplastic-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.
Microplastic pollution and its relationship with the bacterial community in coastal sediments near Guangdong Province, South China
This study systematically characterized microplastic pollution in coastal sediments near Guangdong Province, China, and found that microplastic abundance was linked to changes in the local bacterial community. Higher microplastic levels were associated with shifts in microbial diversity, suggesting plastic pollution can alter the microbial ecology of marine sediments.
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.
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.
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.
Microbial Communities on Plastic Polymers in the Mediterranean Sea
Researchers collected floating microplastics from a bay in the Mediterranean and analyzed their bacterial biofilm communities using 16S rRNA sequencing, finding that microbial communities on plastics were distinct from surrounding seawater and differed between polymer types.
Plastisphere assemblages differ from the surrounding bacterial communities in transitional coastal environments
Researchers found that bacterial communities colonizing plastic particles (the plastisphere) in Portuguese estuarine and beach environments were significantly different from those in surrounding water and sediments, with plastic type and environmental conditions influencing microbial community composition.
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.
Dynamics and functions of microbial communities in the plastisphere in temperate coastal environments
Researchers explored microbial communities colonizing microplastics in coastal environments of Japan, comparing bacterial and fungal communities across different plastic types, water, sediment, and sand. The study found that while microbial communities varied by sample type and location rather than plastic shape, microplastics harbored hydrocarbon-degrading organisms as well as potential pathogens, highlighting the ecological significance of plastic-associated biofilms.
Characteristics of microplastics in different media in Jiaozhou Bay, China
Researchers characterized microplastics in water, sediment, and biological samples from Jiaozhou Bay in China, finding plastics across all environmental compartments. The study documents spatial variation in contamination and highlights the bay as a site of significant plastic accumulation linked to nearby urban and industrial activity.
Diversity and succession of microbial communities on typical microplastics in Xincun Bay, a long-term mariculture tropical lagoon
Researchers tracked microbial community succession on polyethylene, polystyrene, and polypropylene microplastics over 60 days in a tropical mariculture lagoon, finding that plastisphere bacterial diversity exceeded that of surrounding seawater and that community structure shifted significantly over time.
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.
Characteristics of microplastics in different matrices in Jiaozhou Bay, China
Researchers characterized microplastics across multiple matrices (water, sediment, organisms) in Jiaozhou Bay, China to understand coastal pollution patterns. They found widespread microplastic contamination with distinct distribution profiles linked to coastal human activities and identified sources to support pollution mitigation strategies.

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.
An In Situ Study to Understand Community Structure of Estuarine Microbes on the Plastisphere
Researchers performed 16S rRNA sequencing on biofilms from three microplastic polymer types and glass bead controls deployed in Baltimore Inner Harbor over 28 days, finding that plastisphere communities were taxonomically distinct from free-living microbial communities but that polymer type did not significantly differentiate community composition, with Cyanobacteria, Planctomycetes, and sulfate-reducing bacteria among the notable colonizers.
Insight into the bacterial community composition of the plastisphere in diverse environments of a coastal salt marsh
Researchers conducted a year-long field experiment examining microbial communities that colonize different types of microplastics in a Chinese coastal salt marsh across three distinct habitat zones. They found that the type of plastic polymer and the surrounding environment both significantly influenced the composition of the bacterial communities growing on the plastic surfaces. The study reveals that bio-based plastics like polylactic acid harbored distinctly different microbial communities compared to petroleum-based plastics like polyethylene.

[Distribution Characteristics of Microplastic Surface Bacterial Communities Under Flooded and Non-flooded Conditions in Nanjishan Wetland of Poyang Lake].
A 16S sequencing study of bacterial communities in the Poyang Lake wetland found that microbial diversity on microplastic surfaces was lower than in surrounding sediment and water, with the microplastic biofilm community shifting between sediment-like (non-flooded) and water-like (flooded) profiles depending on water level. The plastisphere communities were dominated by distinct bacterial genera including elevated Proteobacteria, suggesting that microplastics select for specific microbial assemblages in natural wetland ecosystems.
