Researchers explored microbial communities colonizing microplastics in coastal environments of Japan, comparing bacterial and fungal communities across different plastic types, water, sediment, and sand.

Discrepancy strategies of sediment abundant and rare microbial communities in response to floating microplastic disturbances: Study using a microcosmic experiment
Using microcosm experiments with fluvial sediment exposed to four plastic types, researchers found that floating microplastics altered sediment microbial diversity and reduced bacteria involved in carbon and nitrogen cycling. Abundant microbial taxa were more sensitive to microplastic disturbance than rare taxa, and microplastics decreased network complexity and increased negative species interactions in microbial communities.
Can Microplastic Pollution Change Important Aquatic Bacterial Communities?
Microplastics in coastal sediments can change the composition of important bacterial communities that cycle nutrients and maintain ecosystem health. Microplastic-associated bacteria differ significantly from natural sediment bacteria, with potential consequences for the chemical processes these communities perform.
Effects of microplastics on the structure and function of bacterial communities in sediments of a freshwater lake
Researchers examined how microplastics alter the structure and function of bacterial communities in sediments, finding that plastic exposure shifted community composition and reduced overall diversity compared to plastic-free controls. Functional analysis showed impaired denitrification and organic matter decomposition in microplastic-contaminated sediments, indicating ecosystem-level consequences for nutrient cycling.

Researchers found that microplastics shape soil microbial communities in paddy soils in ways that affect organic matter decomposition, revealing how bacterial succession and carbon cycling are altered by microplastic presence in agricultural systems.
Shifting enzyme activity and microbial composition in sediment coregulate the structure of an aquatic plant community under polyethylene microplastic exposure
Researchers investigated how polyethylene microplastics affect underwater plant communities and found that the impact varies significantly by species. Canopy-forming plants actually grew more under microplastic exposure, while rosette-forming species declined sharply, shifting the overall community structure. The study suggests that microplastics in freshwater sediments can reshape aquatic ecosystems by altering enzyme activity and microbial composition in ways that favor some plant species over others.

Researchers conducted microcosm experiments to study how polystyrene and polyethylene microplastics of different sizes affect sediment bacterial and fungal communities in Taihu Lake over 60 days. They found that microplastics reduced microbial diversity and significantly altered community structures, with particle size being the most influential factor. The study suggests that microplastic pollution in lake sediments may disrupt natural biogeochemical processes by shifting microbial community composition and network complexity.

Researchers used DNA sequencing to examine how polyethylene microplastics affect soil microbial communities and carbon-nitrogen cycling across soils with different textures. They found that microplastics significantly shifted microbial community composition and altered the abundance of genes involved in carbon and nitrogen transformation, with effects varying by soil type. The study suggests that microplastic contamination may disrupt fundamental nutrient cycling processes differently depending on soil characteristics.

Is soft-sediments ecosystem service delivery compromised due to microplastic pollution?
This review examines how microplastic pollution may compromise ecosystem service delivery in soft-sediment habitats, focusing on potential impacts on microphytobenthic microbial communities that underpin nutrient cycling, sediment stabilization, and food web productivity. The authors argue that because soft sediments act as microplastic sinks, their resident microbial communities face disproportionate exposure, and call for holistic research linking microplastic effects on microbial diversity and biogeochemical function to broader ecosystem service outcomes.

Bacterial 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.

Microplastic effects in aquatic ecosystems with special reference to fungi–zooplankton interaction: identification of knowledge gaps and prioritization of research needs
This review identifies a largely unexplored gap in microplastic research: how plastic pollution affects aquatic fungi and their interactions with zooplankton. Because fungi play critical roles in breaking down dead organic matter and serving as food for zooplankton, disruptions caused by microplastics — which can physically resemble fungal spores in size — could have cascading effects on freshwater food webs and nutrient cycling. The authors call for targeted experiments to fill this knowledge gap and better predict ecosystem-level impacts of microplastic contamination.
