ClearInfluence of biofilms on the adsorption behavior of nine organic emerging contaminants on microplastics in field-laboratory exposure experiments
Researchers studied how natural biofilms that form on microplastics in lake water affect the adsorption of nine emerging organic contaminants. The study found that biofilm colonization on microplastic surfaces can significantly alter how these particles interact with pollutants, in some cases increasing and in others decreasing contaminant uptake compared to clean microplastics.
Impacts of Biofilm Formation on the Fate and Potential Effects of Microplastic in the Aquatic Environment
Researchers reviewed how biofilm formation on microplastic surfaces affects the fate and potential ecological effects of microplastics in aquatic environments, finding that biofilms alter particle buoyancy, surface chemistry, and interactions with organisms.
Effect of Biofouling on the Sorption of Organic Contaminants by Microplastics
Researchers studied how biofilm formation on microplastics affects their ability to absorb organic contaminants in aquatic environments. They found that as biofilms grew over 5 to 15 days on plastic surfaces, the sorption of hydrophilic compounds like methylene blue increased, while hydrophobic compound sorption was less affected. The study suggests that biofouling changes the surface chemistry of microplastics in ways that may alter how they transport different pollutants through water systems.
Biofilm on microplastics in aqueous environment: Physicochemical properties and environmental implications
This review examines how bacteria and other microorganisms form sticky films called biofilms on microplastic surfaces in water. These biofilms change how microplastics move through the environment and increase their ability to absorb pollutants like heavy metals, pesticides, and antibiotics. Biofilm-coated microplastics may also carry harmful bacteria, making them a greater potential health risk than clean microplastic particles.
Impact of Biofilm Formation on Microplastic Behaviour in Aquatic Environments: An Comprehensive Review.
This review examines how biofilms — communities of microorganisms that coat microplastics — change the behavior of plastic particles in aquatic environments, affecting how they move, sink, and interact with ecosystems. Understanding biofilm formation on microplastics is key to predicting where these particles end up and what risks they pose to water quality and aquatic life.
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.
Microplastic-specific biofilm growth determines the vertical transport of plastics in freshwater
Researchers studied biofilm growth on five different microplastic polymer types in freshwater over 63 days to understand how biological colonization affects sinking behavior. The study found that biofilm growth is polymer-specific and can significantly alter the density of microplastic particles, which in turn determines whether they sink or float, influencing their vertical transport through freshwater systems.
Biofilm formation and its influences on the properties of microplastics as affected by exposure time and depth in the seawater
Researchers submerged polyethylene film at three depths in China's Yellow Sea for up to 135 days and tracked how microbial biofilms developed on the plastic over time. They found that biofilm growth increased with exposure time but decreased at greater depths, and the microbial coating changed the surface properties of the plastic, making it less water-repellent. The study demonstrates that biofilm formation on microplastics influences their environmental behavior and ultimate fate in the ocean.
Migration of natural organic matter and Pseudomonas fluorescens-associated polystyrene on natural substrates in aquatic environments
This study examined how a coating of natural organic matter or bacterial biofilm changes the way microplastic particles attach to and move through aquatic surfaces, finding that both coatings altered particle behavior in ways that depended on water salt concentration. Understanding how environmental coatings affect microplastic transport helps predict where particles will ultimately end up — and which organisms are most likely to be exposed.
Physicochemical behavior and ecological risk of biofilm-mediated microplastics in aquatic environments
This review explores how biofilm formation on microplastics in water environments changes their physical and chemical behavior, potentially increasing their ecological risks. Researchers found that biofilm-coated microplastics more readily absorb pollutants and antibiotic resistance genes, and may disrupt gut microbiota in organisms that ingest them. The findings suggest that the biological aging of microplastics in nature makes them more dangerous than freshly produced particles.
Impact of different modes of adsorption of natural organic matter on the environmental fate of nanoplastics
Natural organic matter in water can stabilize nanoplastics by coating their surfaces and preventing them from clumping together and settling out, with different types of organic matter working through different physical mechanisms. Understanding this stabilization effect is important for predicting how long nanoplastics remain suspended in aquatic environments.

Microplastics and organic contaminants: Investigation of the sorption process on different polymer types
Researchers investigated sorption of organic contaminants onto microplastics collected from environmental samples, finding that real-world MPs had different sorption capacities than laboratory-prepared particles due to surface aging, biofouling, and co-sorption of natural organic matter.
In situ biofilm development on microplastics and its impact on PFAS adsorption in aquatic environment
Researchers deployed microplastics in a river system to allow natural biofilm colonization, then assessed how the resulting plastisphere affected PFAS adsorption. Biofilm formation substantially altered PFAS uptake onto microplastics, in some cases increasing adsorption, suggesting that biologically colonized microplastics behave as more effective PFAS carriers than virgin particles in natural water environments.

Biofilm Formation Influences the Wettability and Settling of Microplastics
This study found that biofilm formation on microplastic surfaces does not necessarily increase particle mass density enough to cause sinking, contradicting a common assumption. Instead, changes in particle wettability caused by biofilm were identified as a critical mechanism controlling microplastic vertical transport in the ocean.
