ClearUtilizing Chlorella vulgaris algae as an eco-friendly coagulant for efficient removal of polyethylene microplastics from aquatic environments
Researchers tested the green algae Chlorella vulgaris as an eco-friendly coagulant for removing polyethylene microplastics from water.

Researchers investigated whether exopolysaccharide (EPS) produced by Chlorella vulgaris microalgae can facilitate the removal of polypropylene (PP) and polyethylene terephthalate (PET) microplastics from aquatic systems, while also examining microplastic effects on algal growth. The study demonstrates that EPS functions as a bioflocculant capable of binding microplastics, with implications for biologically-based water treatment.
Influence of microplastics on microalgal performance during wastewater polishing
Researchers studied how five common types of microplastics affect the green alga Chlorella vulgaris during wastewater treatment.

The study demonstrates that Chlorella vulgaris is a robust candidate for bioremediation of microplastic-contaminated wastewater, even under pollutant stress.

Interplay of plastic pollution with algae and plants: hidden danger or a blessing?
Researchers tested the ability of three microalgae species to remove microplastics from water through bioadhesion, finding that all three species could adsorb particles onto their surfaces. Removal efficiency depended on particle size, surface charge, and algae cell morphology.
Adverse effects of microplastics observed on the growth rate and health of the freshwater alga, Chlorella sp. 12.

Microalgae separation in MP-PVC contaminated wastewater using plant-based coagulant over different extraction methods in Bauru, Brazil
Researchers tested Moringa oleifera plant extracts as natural coagulants for removing microalgae and PVC microplastics from photobioreactor wastewater, achieving over 83% turbidity removal and 63% microplastic removal under optimized conditions. Plant-based coagulants are a more sustainable and lower-cost alternative to synthetic chemical flocculants, and this study demonstrates they can handle the combined challenge of microalgae and microplastic removal simultaneously.
Influence of polystyrene microplastics on levofloxacin removal by microalgae from freshwater aquaculture wastewater
Researchers found that polystyrene microplastics inhibited Chlorella vulgaris growth and reduced its efficiency in removing the antibiotic levofloxacin from freshwater aquaculture wastewater, demonstrating that microplastic pollution can impair microalgae-based water treatment systems.

Not relevant to microplastics — this study tests the green macroalga Ulva intestinalis as a low-cost biosorbent for removing phenol from industrial wastewater, with no connection to plastic particle pollution.
Extensive investigation and beyond the removal of micro-polyvinyl chloride by microalgae to promote environmental health
Researchers found that Chlorella sp. microalgae can effectively remove micro-polyvinyl chloride particles from water, though PVC exposure at high concentrations triggered oxidative stress responses, suggesting algae-based remediation as a promising strategy for microplastic pollution.
Effects of different concentrations and particle sizes of microplastics on the full life history of freshwater Chlorella
Researchers investigated how polystyrene microplastics of different concentrations and particle sizes affect the complete life cycle of freshwater Chlorella algae.

Recent progress on the toxic effects of microplastics on Chlorella sp. in aquatic environments
This review summarizes research on how microplastics affect Chlorella, a type of green algae that forms the base of aquatic food chains. Microplastics can slow algae growth, cause oxidative stress, and disrupt photosynthesis, which matters for human health because damage to these foundational organisms can ripple up through the food web and affect the quality of water and seafood.

Researchers tested how polyethylene and polystyrene microplastics affect the freshwater algae Chlorella vulgaris and found that smaller particles and higher concentrations caused more harm. The microplastics reduced algal growth, photosynthetic efficiency, and disrupted nutrient composition over the 11-day experiment. Since algae form the base of aquatic food chains, this damage could ripple upward through ecosystems that ultimately connect to human food sources.

Effective removal of microplastics by filamentous algae and its magnetic biochar: Performance and mechanism
Researchers found that filamentous algae and a magnetic biochar made from the algae can effectively remove microplastics from water, with the biochar absorbing over 215 milligrams of microplastics per gram. The algae naturally trap microplastics through entanglement and adhesion, while the magnetic biochar can be easily recovered from water using magnets. This dual approach could help address both algae bloom problems and microplastic contamination in urban water systems.
Investigation of the Migration Patterns for Nanoplastics With Different Sizes in Chlorella vulgaris and Their Effects on Heavy Metal Adsorption by the Microalgae
Scientists found that tiny plastic particles (nanoplastics) can get absorbed by algae, with smaller particles entering the algae cells while larger ones stick to the surface. These plastic particles change how the algae absorb toxic heavy metals like mercury, cadmium, and lead from water. This matters because it could affect how these dangerous metals move through the food chain and potentially reach humans who eat seafood or use algae-based products.
