Impacts of Biofilm Formation on the Fate and Potential Effects of Microplastic in the Aquatic Environment
AI summary Read the abstract
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.
In the aquatic environment, microplastic (MP; <5 mm) is a cause of concern because of its persistence and potential adverse effects on biota. Studies of microlitter impacts are mostly based on virgin and spherical polymer particles as model MP. However, in pelagic and benthic environments, surfaces are always colonized by microorganisms forming so-called biofilms. The influence of such biofilms on the fate and potential effects of MP is not understood well. Here, we review the physical interactions of early microbial colonization on plastic surfaces and their reciprocal influence on the weathering processes and vertical transport as well as sorption and release of contaminants by MP. Possible ecological consequences of biofilm formation on MP, such as trophic transfer of MP particles and potential adverse effects of MP, are virtually unknown. However, evidence is accumulating that the biofilm−plastic interactions have the capacity to influence the fate and impacts of MP by modifying the physical properties of the particles. There is an urgent research need to better understand these interactions and increase the ecological relevance of current laboratory testing by simulating field conditions in which microbial life is a key driver of biogeochemical processes.

Impact of Biofilm Formation on Microplastic Behaviour in Aquatic Environments: An Comprehensive Review.
AI summary Read the abstract
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.
Biofilm formation and its implications on the properties and fate of microplastics in aquatic environments: A review
AI summary Read the abstract
Researchers reviewed how microplastics in water attract and support communities of bacteria and other microorganisms that form biofilms — living coatings that alter the plastic particles' movement, help them carry pathogens, and affect how toxic chemicals attached to the plastic are absorbed by living things. Understanding this "plastisphere" ecosystem is critical for predicting where microplastics go and how harmful they become.

This review examines how biofilms — communities of microorganisms that form on microplastic surfaces — affect the fate and ecological effects of plastic pollution. Biofilm formation alters how microplastics are transported, ingested, and degraded in the environment, and the plastisphere can harbor pathogens and antibiotic-resistant bacteria that may pose risks to human health.
Biofilm on microplastics in aqueous environment: Physicochemical properties and environmental implications
AI summary Read the abstract
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.
