ClearBacterial 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.
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.
Comparative analysis of microplastic and microbial communities in varied aquatic environments: Disparities in occurrence, interconnections, and ecological implications
Comparative surveys of microplastics and associated microbial communities across river, reservoir, and bay environments in the Dongjiang watershed found that MP abundance and microbial community composition differed significantly by water type, with MP surfaces hosting distinct microbial assemblages.
Quantifying the Impact of Multiple Stressors on Microbial Communities in Dianshan Lake Sediments Using Random Forest Analysis
Researchers quantified the combined impact of nutrient pollution and microplastic contamination on microbial community diversity and function in Diansha Lake, Shanghai. Multiple stressor interactions produced non-additive effects on microbial communities, with microplastics altering how microbial populations responded to nutrient enrichment.
Impact of microplastics on microbial community in sediments of the Huangjinxia Reservoir—water source of a water diversion project in western China
Researchers examined microplastic contamination and its effects on microbial communities in sediments of the Huangjinxia Reservoir in western China, investigating how microplastic presence alters the composition and function of microbial assemblages in this drinking water source.
In Situ Investigation of Plastic-Associated Bacterial Communities in a Freshwater Lake of Hungary
Researchers investigated plastic-associated bacterial communities on microplastic surfaces in a Hungarian freshwater lake, finding that the plastisphere harbored distinct microbial communities compared to surrounding water, including potential pathogens and plastic-degrading bacteria.
[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.
Abundance and characteristics of microplastics in the surface water and sediment of parks in Xi'an city, Northwest China
Researchers surveyed microplastic pollution in urban park water bodies and sediments across Xi'an city, finding concentrations of 2,900-6,970 items per cubic meter in surface water, with distribution patterns linked to surrounding urban land use functions.
Rapid urbanization affects microplastic communities in lake sediments: A case study of Lake Aha in southwest China
Researchers investigated how rapid urbanization affects microplastic communities in Lake Aha sediments in southwest China, using sediment core slicing to reveal that urbanization significantly increased microplastic abundance and altered polymer composition over time.
Distinct microbial communities in the microplastisphere of inland wetlands: Diversity, composition, co-occurrence networks, and functions.
Researchers collected samples from different inland wetland types to characterize the microbial communities colonizing plastic surfaces (the microplastisphere), finding distinct bacterial and fungal communities compared to surrounding soils. Community composition varied by wetland type and plastic surface, highlighting the ecological diversity of plastic-associated microbiomes in freshwater habitats.
Microplastic Pollution in Surface Water of Urban Lakes in Changsha, China
Microplastic concentrations were measured in eight urban lakes in Changsha, China, with researchers finding widespread contamination and identifying local land use and hydrological connectivity as key factors influencing microplastic abundance.
Identifying Microbial Distribution Drivers of Archaeal Community in Sediments from a Black-Odorous Urban River—A Case Study of the Zhang River Basin
This study investigated how urbanization, eutrophication, and heavy metal pollution shape archaeal (ancient microbial) community composition in sediments of blackened, odorous urban rivers. Understanding microbial responses to these stressors helps track the health of aquatic ecosystems heavily impacted by pollution, including microplastics.

This study explored the relationships between microplastics, microorganisms, and water quality in China's Xiangjiang River, a source of urban drinking water. Researchers found that microplastic levels were higher near urban areas and wastewater plant outlets, and that the smallest particles showed the strongest correlations with microbial community changes, suggesting complex interactions between plastic pollution and river ecosystems.
Sediment bacterial and fungal communities exhibit distinct responses to microplastic types and sizes in Taihu lake
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.
