ClearCombined influence of the nanoplastics and polycyclic aromatic hydrocarbons exposure on microbial community in seawater environment
Researchers studied the individual and combined effects of nanoplastics and polycyclic aromatic hydrocarbons on microbial communities in seawater. They found that the combination of these two pollutants altered microbial diversity and community structure differently than either pollutant alone. The study suggests that the interaction between nanoplastics and chemical pollutants in the ocean may have complex and unpredictable effects on marine microbial ecosystems.
MicrobialDynamics on Different Microplastics in CoastalUrban Aquatic Ecosystems: The Critical Roles of Extracellular PolymericSubstances
Researchers investigated microbial community composition and extracellular polymeric substance secretion across plastispheres formed on different microplastic types at two coastal urban water sites, using permutational multivariate analysis to show that microplastic type significantly shaped microbial community structure. The findings reveal that EPS production and microbial colonization patterns vary systematically with polymer chemistry, influencing plastisphere ecology.
The structure and assembly mechanisms of plastisphere microbial community in natural marine environment
Researchers investigated how microbial communities colonize different types of microplastic surfaces in natural marine environments over an eight-week period. They found that the composition of these plastic-associated microbial communities, known as the plastisphere, was shaped more by environmental conditions and time than by the specific type of plastic. The study provides new understanding of the ecological processes governing how microorganisms assemble on ocean plastic debris.
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.
The co-presence of polystyrene nanoplastics and ofloxacin demonstrates combined effects on the structure, assembly, and metabolic activities of marine microbial community
Researchers examined the combined effects of polystyrene nanoplastics and the antibiotic ofloxacin on marine microbial communities. They found that the two pollutants together had a greater impact on bacterial community structure and metabolic activity than either one alone. The study suggests that nanoplastics and antibiotics co-occurring in the ocean may work together to disrupt the microorganisms that support marine ecosystem health.
Microplastic-Associated Biofilms and Their Role in the Fate of Microplastics in Aquatic Environment
This review examines how microbial biofilms attached to microplastics in aquatic environments mediate the accumulation and transfer of chemical pollutants, exploring how the 'plastisphere' community influences the fate and ecotoxicological impact of microplastics and co-contaminants.
Unique Bacterial Community of the Biofilm on Microplastics in Coastal Water
Researchers compared bacterial communities forming biofilms on steel, silica, and PVC microplastic surfaces in coastal seawater and found that biofilm composition differed by material type. This shows that the type of plastic surface influences which microbial communities colonize it, with implications for how microplastics may spread specific bacteria.
Effect of flumetsulam alone and coexistence with polyethylene microplastics on soil microbial carbon and nitrogen cycles: Elucidation of bacterial community structure, functional gene expression, and enzyme activity
Researchers tested how the herbicide flumetsulam interacts with polyethylene microplastics in soil and found that both individually and together they reduced bacteria and fungi populations. When microplastics were present alongside the herbicide, the soil bacterial community shifted more dramatically, though carbon and nitrogen cycling remained largely unchanged. The study suggests that the combined presence of herbicides and microplastics in agricultural soil creates distinct effects on microbial life compared to either contaminant alone.
The ecology of the plastisphere: Microbial composition, function, assembly, and network in the freshwater and seawater ecosystems
Researchers studied the communities of bacteria and fungi that colonize microplastic surfaces in freshwater and seawater, forming what scientists call the plastisphere. These microplastic-associated communities were distinctly different from those in surrounding water, and included a higher proportion of disease-causing organisms and species involved in pollutant degradation. The findings suggest that microplastics create new habitats that can harbor pathogens and alter natural microbial ecosystems in ways that may affect water quality and human health.
The composition of bacterial communities associated with plastic biofilms differs between different polymers and stages of biofilm succession
Researchers tracked bacterial community development on five different plastic types submerged in coastal waters over two months. They found that bacterial community composition varied by both plastic type and stage of colonization, with distinct early and late succession patterns. The study provides evidence that different plastics may host different microbial communities, which has implications for understanding how plastic pollution influences marine microbial ecology.
A review on microbial-biofilm mediated mechanisms in marine microplastics degradation
This review examines how microbial biofilms form on microplastics in marine environments and their potential role in degrading these persistent pollutants. Researchers found that plastic-associated biofilm communities are diverse and influenced by factors such as polymer type, particle size, and seasonal conditions. The study identifies knowledge gaps in understanding how bacterial and fungal communities on microplastics may contribute to their breakdown in ocean environments.

Microplastics reduce soil microbial network complexity and ecological deterministic selection
Researchers found that microplastics reduce soil microbial network complexity and shift community assembly from deterministic to more stochastic processes, suggesting that microplastic pollution may fundamentally alter microbial ecological interactions in terrestrial systems.
Microplastics in the marine environment : an ecotoxicological perspective
This doctoral thesis studied the ecotoxicology of marine plastic pollution, examining how microplastics and plastic-associated chemicals affect microbial communities, algae, and invertebrates. The work found that the plasticizer microbiome — bacteria colonizing plastic surfaces — differs from surrounding seawater and may influence how plastic-associated pollutants move through food webs.
Combined environmental pressure induces unique assembly patterns of micro-plastisphere biofilm microbial communities in constructed wetlands
Researchers studied how biofilm communities form on microplastic surfaces within constructed wetlands used for wastewater treatment. They found that environmental stressors like antibiotics and organic matter created unique microbial communities on microplastics that differed from those on natural surfaces. The study suggests that constructed wetlands, while effective at trapping microplastics, may also foster distinct microbial ecosystems on plastic surfaces that warrant further investigation.
Microbial Dynamics on Different Microplastics in Coastal Urban Aquatic Ecosystems: The Critical Roles of Extracellular Polymeric Substances
Researchers investigated how microbial communities colonize different types of microplastics in urban coastal waters, forming distinct ecosystems known as plastispheres. They found that the type of plastic significantly shaped which bacteria grew on it and how much sticky extracellular material they produced. Understanding these microbial communities on microplastics matters because they can harbor harmful bacteria and influence how pollutants move through aquatic environments.
