ClearDynamics 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.
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.
A close relationship between microplastic contamination and coastal area use pattern
Researchers investigated microplastic contamination across three coastal areas in Korea characterized by different human activities: urban, aquafarm, and rural. They found that microplastic abundance and polymer composition varied by area, with diverse polymers at urban sites, polystyrene dominant near aquaculture operations, and polypropylene prevalent at rural fishing sites. The study demonstrates a close relationship between coastal land use patterns and the characteristics of microplastic pollution in both abiotic and biotic samples.
Associations between bacterial communities and microplastics from surface seawater of the Northern Patagonian area of Chile
Researchers characterized bacterial communities on microplastics collected from three coastal sites with varying aquaculture activity in Chilean Patagonia, identifying 3,102 OTUs dominated by Cyanobacteria, Bacteroidetes, and Proteobacteria, with communities differing from surrounding seawater at all sites. Despite site-specific variation, 222 bacterial OTUs were shared across all three locations, suggesting a core plastisphere community that persists across different anthropogenic conditions.
Comparative microbial communities in tidal flats sediment on Incheon, South Korea
The microbial communities in tidal flat sediments in South Korea were characterized and found to be highly diverse, playing important roles in coastal nutrient cycling. Understanding natural microbial communities in coastal sediments provides context for assessing how microplastic-associated microorganisms alter these ecosystems.
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.
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.
A Study on the Distribution of Microplastics in the South Coast of Korea and Gwangyang Bay
This study characterized the distribution and abundance of microplastics in surface water along the south coast of South Korea, finding widespread contamination with fibers and fragments across multiple sampling sites. Polymer analysis identified polyethylene, polypropylene, and polystyrene as the dominant types.
Abundance and Distribution Characteristics of Microplastics in Surface Seawaters of the Incheon/Kyeonggi Coastal Region
Researchers investigated microplastics in both the surface microlayer and subsurface waters of the Incheon/Kyeonggi coastal region of Korea, finding that microplastic concentrations were significantly higher in the surface microlayer than in bulk seawater. Fragment and fiber morphologies dominated, with the distribution patterns reflecting urban runoff and shipping activity as likely sources.
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.
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.
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.
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.
