ClearStudy of the Bacterial, Fungal, and Archaeal Communities Structures near the Bulgarian Antarctic Research Base “St. Kliment Ohridski” on Livingston Island, Antarctica
Not relevant to microplastics — this paper profiles the microbial communities (bacteria, fungi, archaea) found near a Bulgarian Antarctic research station, finding diverse and largely unidentified species with potential biotechnological uses.
Microplastic impacts archaeal abundance, microbial communities, and their network connectivity in a Sub-Saharan soil environment
Researchers used 16S rRNA amplicon sequencing to characterise prokaryotic communities in native plastisphere and soil from Sub-Saharan African environments with high unmanaged plastic waste. The plastisphere enriched distinct bacterial communities and archaeal taxa compared to surrounding soil, and high-population sites showed elevated potential pathogen abundance.
Plastisphere colonization in Antarctica: a microcosmos approach
Researchers conducted a 33-day microcosm experiment incubating polypropylene, polyester, polystyrene, and quartz fragments in Antarctic seawater and used SEM, flow cytometry, qPCR, and metagenomics to characterize bacterial plastisphere colonization, finding that microbial community composition was driven primarily by incubation time rather than polymer type, with Oleispira potentially involved in hydrocarbon degradation.
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.
Diverse groups of fungi are associated with plastics in the surface waters of the Western South Atlantic and the Antarctic Peninsula
DNA metabarcoding of fungi on marine plastic debris from the Western South Atlantic and Antarctic Peninsula revealed 64 orders across eight fungal phyla, including many taxa not previously described on plastic surfaces. The study is the first to characterize the plastic-associated fungal communities of the Southern Hemisphere, highlighting the unknown ecological roles of plastic-colonizing fungi.
The Culturable Mycobiota of Sediments and Associated Microplastics: From a Harbor to a Marine Protected Area, a Comparative Study
Researchers investigated fungal diversity in sediments and microplastic surfaces at three Mediterranean sites with varying anthropogenic impact -- a harbor, a marine protected area, and an intermediate site -- culturing 1,526 isolates and finding that microplastics harbor distinct fungal assemblages compared to surrounding sediments, with several species recorded for the first time in marine environments.
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.
Prokaryotic Diversity and Community Patterns in Antarctic Continental Shelf Sponges
Antarctic sponges were found to host diverse communities of bacteria, some of which produce potentially useful bioactive compounds. This is a microbial ecology study not directly related to microplastics.
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.
Spatio-temporal variation of bacterial community structure in two intertidal sediment types of Jiaozhou Bay
This is a microbial ecology study characterizing bacterial communities in intertidal sediments of Jiaozhou Bay, China, using 16S rRNA gene sequencing; it is not a microplastics research paper.
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.
Contribution of Research Station Activities to Microplastic Pollution in Antarctica: A Case Study of King Sejong Station
Researchers monitored microplastic pollution from King Sejong Antarctic research station over time to assess whether local station activities contribute meaningfully to MP contamination. Frequent temporal sampling linked station operations to detectable MP pollution in surrounding environments, suggesting research stations are a locally significant source beyond ocean-transported plastics.
Exploring the Microdiversity Within Marine Bacterial Taxa: Toward an Integrated Biogeography in the Southern Ocean
Researchers used advanced sequencing techniques to study the fine-scale diversity and geographic distribution of bacteria in the Southern Ocean. Understanding ocean microbial communities is relevant to microplastic research because plastics in the ocean host distinct microbial communities that can alter local ecology.
Microplastics in sediments of the waters near the Akademik Vernadsky station
Researchers examined microplastic distribution in bottom sediments near the Akademik Vernadsky Antarctic research station, identifying artificial polymer particles in geological components and adapting analytical methods to characterize polar microplastic contamination driven by station activities and regional transport.
Determination of the presence of microplastics in intertidal sediments of deception island, antarctica
Researchers determined the presence and characteristics of microplastics in intertidal sediments of Deception Island, Antarctica, providing evidence that plastic contamination has reached one of Earth's most remote environments and documenting the role of marine sediments as sinks for persistent microplastic pollution.
Effects of microplastics on cold seep sediment prokaryotic communities
Researchers studied how polyethylene, polystyrene, and polypropylene microplastics affect microbial communities in cold seep sediments over a 120-day incubation period. The study found that microplastics significantly altered bacterial community structure in a type- and concentration-dependent manner, with some bacteria associated with plastic degradation increasing, while archaeal communities were less affected.
Arctic macrosources of the microplastic pollution (Longyearbyen, Spitsbergen): Spectral characterization and first insight into the fungal diversity on the arctic plastisphere
Researchers identified local plastic macro- and meso-litter on an Arctic beach in Longyearbyen (Spitsbergen) as composed predominantly of polyethylene (64%), polypropylene (27%), and polystyrene (9%), and isolated 20 fungal taxa from the plastisphere — including 4 previously unreported from Svalbard — suggesting plastics may act as vectors for alien fungal species in the Arctic.
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.
Plastisphere colonization in Antarctica: a microcosmos approach
Researchers investigated the Antarctic plastisphere by incubating polypropylene, polyester, polystyrene, and quartz fragments in seawater microcosms for 33 days, using SEM, flow cytometry, qPCR, and metagenomics to track microbial colonization dynamics. They found that biofilm formation occurred rapidly but at slower growth rates than other oceanic regions, with time rather than polymer type driving community succession, and identified Oleispira as a genus of interest for potential hydrocarbon degradation.
Advocating microbial diversity conservation in Antarctica
This review highlights how human activities, tourism, and climate change are threatening Antarctica's unique microbial ecosystems, with microplastics now reaching even this remote continent. While focused on conservation, the study underscores that microplastic pollution is truly global in scale, contaminating environments far from any source of plastic production.
Spatio-temporal distribution of soil microbial communities and nutrient availability around a municipal solid waste landfill
Despite its title referencing soil microbial communities near a municipal solid waste landfill, this paper studies bacterial and fungal community composition in soils surrounding a landfill — not microplastic pollution. It examines how proximity to the landfill affects microbial diversity and nutrient cycling and is not directly relevant to microplastics or human health.
