ClearStudy of Heavy Metals and Microbial Communities in Contaminated Sediments Along an Urban Estuary
Researchers studied heavy metal contamination and microbial community composition in estuarine sediments along an urban waterway, finding that urbanization-driven metal accumulation significantly altered microbial diversity and community structure.
Functional responses of key marine bacteria to environmental change – toward genetic counselling for coastal waters
This review examined the functional responses of key marine bacteria to environmental stressors including nutrient pollution and chemical contamination in coastal ecosystems, arguing that bacteria are overlooked both as indicators and mediators of ecosystem health. The authors call for incorporating bacterial functional metrics into marine ecosystem monitoring and management frameworks.
Genomic and proteomic profiles of biofilms on microplastics are decoupled from artificial surface properties
Genomic and proteomic analysis of biofilms on marine microplastics showed that community composition and functional profiles were primarily shaped by environmental conditions rather than the specific surface properties of the plastic substrate.
Metal leaching from plastics in the marine environment: An ignored role of biofilm.
Researchers investigated how biofilms on marine plastics influence metal leaching, finding that microbial colonization significantly alters the release rates of metal additives from common polymers, representing a previously underappreciated pathway for heavy metal transfer from plastic debris into marine ecosystems.
[Community Structure and Microbial Function Responses of Biofilms Colonizing on Microplastics with Vertical Distribution in Urban Water].
Biofilm communities colonizing microplastics at different depths in urban water bodies were found to differ significantly in community structure and metabolic function. Microplastics at different depths were exposed to varying light, oxygen, and nutrient conditions, which shaped the attached microbial communities. Understanding how microplastics host distinct microbial assemblages is important for assessing their role as vectors for pathogens and chemical pollutants.
The microbial community of rust layer biofilm was driven by seawater microbial community
This study found that the microbial community colonizing rust layers on submerged metal structures is largely shaped by surrounding seawater microbes. Understanding how marine bacteria colonize surfaces is relevant to the plastisphere — the distinct microbial communities that form on floating microplastic particles in the ocean.
Seawater copper content controls biofilm bioaccumulation and microbial community on microplastics
Researchers found that seawater copper concentration controls both the microbial community composition of biofilms on microplastics and the amount of copper bioaccumulated in those biofilms, demonstrating that metal pollution levels in seawater influence the ecological and chemical behavior of the 'plastisphere'.
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.
Distinct community structure and microbial functions of biofilms colonizing microplastics
Biofilm communities were established on polyethylene, polypropylene, cobblestone, and wood substrates over 21 days under controlled conditions and compared by 16S rRNA sequencing, finding that plastic substrates harbored distinct microbial communities and functional profiles compared to natural materials. The study demonstrates that microplastics in freshwater environments provide a selective niche that enriches for distinct microbial taxa and metabolic functions.
[Applications of biofilm in environmental pollution control and the related challenges].
This review examines biofilm structure, formation mechanisms, and community composition as applied to environmental pollution control, covering removal of heavy metals and organic pollutants, and discussing emerging challenges including plastisphere dynamics, antibiotic resistance gene spread, and pathogen accumulation in biofilm-pollutant interactions.
Evaluation of prokaryotic and eukaryotic microbial communities on microplastic‐associated biofilms in marine and freshwater environments
Researchers analyzed microbial biofilm communities on microplastic surfaces in both marine and freshwater environments, finding that plastic-associated biofilms harbor distinct prokaryotic and eukaryotic communities with potential roles in plastic biodegradation.
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 Nanoplastics on Freshwater Biofilm Microbial Metabolic Functions as Determined by BIOLOG ECO Microplates
Nanoplastics were found to significantly alter the metabolic functions of freshwater biofilm microbial communities, as measured by BIOLOG ECO microplates, with effects varying by concentration and polymer type. The disruption of biofilm microbial metabolism by nanoplastics could have cascading effects on nutrient cycling in freshwater ecosystems.
Sorption behavior of Pb(II) onto polyvinyl chloride microplastics affects the formation and ecological functions of microbial biofilms
Researchers found that lead sorption onto PVC microplastics significantly affected microbial biofilm formation and ecological functions, with lead-enriched microplastics altering biofilm community structure and metabolic activities in aquatic systems.
Microbial community structure and co-occurrence network stability in seawater and microplastic biofilms under prometryn pollution in marine ecosystems
Researchers studied how the herbicide prometryn affects microbial communities in both seawater and on microplastic surfaces in marine environments. They found that prometryn pollution significantly altered the structure and stability of microbial networks growing on microplastics compared to those in surrounding water. The findings suggest that the combination of chemical pollutants and microplastics creates distinct ecological impacts on marine microbial ecosystems.

Biofilm facilitates metal accumulation onto microplastics in estuarine waters
This study demonstrated that biofilm colonization on microplastics in estuarine waters significantly enhanced their sorption of metals such as copper and zinc, suggesting biofouling changes the contaminant-carrying capacity of plastic debris.
The effects of metals and polymer types on the development of biofilm on microplastic surface
Researchers examined biofilm development on three polymer types (PVC, polystyrene, and polyethylene) in the presence of three heavy metals (lead, chromium, and cadmium) to determine how metal contamination influences the formation and composition of plastisphere communities. The study assessed whether metal-microplastic co-contamination alters the structure of microbial biofilms that colonize plastic surfaces in aquatic environments.
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.
Colonization characteristics and surface effects of microplastic biofilms: Implications for environmental behavior of typical pollutants
This review examines how bacteria colonize microplastic surfaces in water, forming biofilms that change how the plastics behave in the environment. These biofilms alter the surface properties of microplastics and affect how they absorb and transport heavy metals and other pollutants. Understanding biofilm formation on microplastics is important because it can make the particles more dangerous by concentrating toxic substances that could eventually enter the food chain.
