This review examined the interactions between micro/nanoplastics and microalgae in aquatic environments, summarizing how plastic particle size, surface chemistry, and co-pollutants influence algal toxicity through oxidative stress, photosynthesis inhibition, and gene expression changes.
Microalgae-based bioremediation of refractory pollutants: an approach towards environmental sustainability
This review examines how microalgae can be used to clean up hard-to-remove pollutants, including microplastics, from contaminated environments. The authors highlight that microalgae-based bioremediation is a sustainable, eco-friendly approach that could help address the growing problem of microplastic pollution in waterways.
Are algae a promising ecofriendly approach to micro/nanoplastic remediation?
This review examines the potential of algae as an eco-friendly approach to removing micro- and nanoplastics from wastewater treatment plant effluents, covering mechanisms including interception, entanglement, and heteroaggregation. Algae also offer the added benefit of nutrient recovery from wastewater and can be further processed into biochar or biofertilizer.
Algae for plastic biodegradation
This review examines how algae interact with microplastics in marine environments, both as organisms harmed by plastic pollution and as potential agents for plastic biodegradation. Microplastics reduce algal photosynthesis and growth, while algal extracellular polymeric substances can trap and sink microplastic particles. Algae-driven biodegradation represents a promising avenue for reducing the persistence of microplastic contamination in the ocean.
Exploring the Potential of Algae in the Mitigation of Plastic Pollution in Aquatic Environments
This review examined how algae can help mitigate plastic pollution in aquatic environments, finding that certain algal species can adsorb, degrade, or entrap microplastics, suggesting potential bioremediation applications though large-scale effectiveness remains to be demonstrated.
Microalgae–microplastics interactions at environmentally relevant concentrations: Implications toward ecology, bioeconomy, and UN SDGs
This study investigated how microalgae interact with microplastics at environmentally relevant concentrations, examining growth inhibition, aggregation, and photosynthetic effects, with implications for aquatic ecosystem function and the feasibility of microalgae-based bioremediation.
Microplastic interactions with freshwater microalgae: Hetero-aggregation and changes in plastic density appear strongly dependent on polymer type
Researchers studied interactions between microplastics and freshwater microalgae, finding that microplastics can physically attach to algal cells to form hetero-aggregates, altering both particle behavior and algal physiology.

This book chapter reviews how microalgae can simultaneously address microplastic removal from aquatic environments and serve as feedstock for biofuel production, presenting the dual-benefit approach as a promising strategy for sustainable environmental remediation.
Distribution of Microplastics and Nanoplastics in Aquatic Ecosystems and Their Impacts on Aquatic Organisms, with Emphasis on Microalgae
This review covers the distribution of microplastics and nanoplastics in aquatic ecosystems and their impacts on aquatic organisms from bacteria to fish, with a focus on effects on microalgae as primary producers. The authors highlight that nanoplastics may be more biologically active than microplastics due to their size and surface reactivity, warranting greater research attention.
A critical review of interactions between microplastics, microalgae and aquatic ecosystem function
This review of microplastic-microalgae interactions found that microplastics form distinct epiplastic algal communities that differ from surrounding water communities, and that the interactions are bidirectional — MP properties affect algal physiology while algal surface coatings alter MP behavior and fate.

A critical review on remediation of microplastics using microalgae from aqueous system
This review explores using microalgae -- tiny photosynthetic organisms -- as a natural way to remove microplastics from water. Microalgae can capture and clump microplastic particles together, making them easier to filter out. Since microplastics in water systems are a growing concern for human health through drinking water and seafood, biological removal methods like this could offer a more sustainable cleanup approach.
Efficiency of Microalgae Employment in Nutrient Removal (Nitrogen and Phosphorous) from Municipal Wastewater
This review examines how microalgae (tiny aquatic plants) can be used to remove nitrogen and phosphorus pollutants from municipal wastewater. While not directly about microplastics, this research is relevant because effective wastewater treatment is one way to reduce the amount of microplastics that reach waterways and eventually the food chain.
