Microbial Communities on Microplastics Highlights Microbial Diversity and Metabolic Role
Summary
Tiny plastic particles in our water don't travel alone — they get coated in layers of bacteria (called biofilms) that can trap and concentrate harmful chemical pollutants, sometimes at levels far higher than in the surrounding water. This coating actually helps the plastic last longer and travel further, meaning these contaminant-carrying particles can build up in fish and other seafood we eventually eat. This chapter reviews existing research on the topic rather than presenting new experiments, but it highlights an important concern: microplastics may act as delivery vehicles for pollutants and microbes moving through the food chain.
Microplastics (MPs) infiltrate aquatic ecosystems, where they endure for extended durations and engage with biotic entities, resulting in significant ecological disruptions. They possess the capacity to engage with chemical contaminants. These compounds can attach to the surface of MPs or infiltrate deeper into the bulk phase, where they can accumulate to levels much exceeding those of the surrounding water. The formation of biofilms on MPs can enhance their durability and mobility, resulting in elevated concentrations in aquatic ecosystems and a heightened risk of harm to aquatic animals. This chapter underscores the dual significance of biofilms on MPs, emphasizing their adverse effects and potential beneficial applications, their chemical composition, the nature of biofilm interactions with these pollutants, and the various factors influencing the contamination of MPs, and offers a comprehensive review of documented biofilm formation levels on contaminated MPs in aquatic environments.
