Microplastic characteristics differentially influence cyanobacterial harmful algal bloom microbial community membership, growth, and toxin production
Researchers investigated how different types of microplastics influence the growth and toxin production of harmful algal blooms in freshwater. They found that certain microplastic characteristics, such as shape and polymer type, significantly affected which microbial species thrived and how much toxin was produced. The study suggests that microplastic pollution may play an underappreciated role in worsening harmful algal blooms in lakes and reservoirs.

A comprehensive assessment of microplastic pollution in China's Yellow River found average abundances of 5,358–654,000 items/m³ in water and 43.57–615 items/kg in sediment, with fibers dominant in water samples, and reviewed evidence of biotoxicity in fish, invertebrates, and microorganisms.
Finding the missing piece of the aquatic plastic pollution puzzle: Interaction between primary producers and microplastics
This review examines the understudied interactions between microplastics and aquatic primary producers such as algae and cyanobacteria. Evidence indicates that microplastics can alter photosynthesis, growth rates, gene expression, and colony morphology in these organisms, potentially through adhesion or transfer of adsorbed pollutants. The authors argue that understanding microplastic impacts on primary producers is a critical missing piece in assessing the full ecological consequences of plastic pollution in aquatic ecosystems.
Characteristics of microplastic pollution and analysis of colonized-microbiota in a freshwater aquaculture system.
Researchers found microplastics averaging 288.53 items per liter in freshwater aquaculture ponds in China, dominated by transparent fibers and cellulose particles, and discovered that bacterial communities on microplastic surfaces had significantly higher species richness and diversity than those in surrounding water. The plastisphere communities were enriched with Proteobacteria, including cellulose-degrading and potentially pathogenic species.
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.
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.
Vertical distribution characteristics of microplastics and bacterial communities in the sediment columns of Jianhu lake in China
Researchers examined microplastic abundance, morphology, and polymer types alongside bacterial community composition in sediment columns (0-60 cm depth) of Jianhu Lake, China, finding microplastic concentrations of 624-3050 particles/kg with rayon, PET, and SBS as dominant polymers, and revealing correlations between microplastic characteristics and bacterial community structure via co-occurrence network analysis.
Meta-analysis for systematic review of global micro/nano-plastics contamination versus various freshwater microalgae: Toxicological effect patterns, taxon-specific response, and potential eco-risks
A meta-analysis of 1,071 observations found that nanoplastics cause more severe cell membrane damage than microplastics, while microplastics more strongly inhibit photosynthesis in freshwater microalgae. Among polymer types, polyamide caused the highest growth inhibition, polystyrene induced the most toxin release, and diatoms were the most sensitive algal group while cyanobacteria showed exceptional resilience.
Microplastics can alter phytoplankton community composition
Researchers tested how microplastic fibers affect natural communities of tiny aquatic organisms called phytoplankton, which form the base of aquatic food webs. At higher concentrations, microplastics significantly shifted the community makeup, boosting certain cyanobacteria while reducing other species. The study suggests that growing microplastic pollution could reshape the foundation of aquatic ecosystems in heavily polluted waterways.

Elucidation of Mechanisms by Which Microplastics (PET) Facilitates the Rapid Growth of Benthic Cyanobacteria and Toxin Production in Aquatic Ecosystems
This review examines how PET microplastics and their chemical leachates may promote the growth of benthic cyanobacteria in aquatic environments. The study suggests that PET-derived compounds can serve as carbon sources or signaling molecules that alter gene expression related to photosynthesis and stress responses, potentially contributing to harmful cyanobacterial blooms in plastic-polluted waters.
Effects of microplastics on coastal planktonic community
This book chapter reviews how microplastics affect coastal phytoplankton communities, covering physical clogging, chemical toxicity, and disruption of photosynthesis and cell division across diatoms, dinoflagellates, and cyanobacteria. Since phytoplankton form the base of marine food webs and produce roughly half of Earth's oxygen, widespread microplastic-driven decline in these communities would have cascading consequences for ocean ecosystems and global climate.
Microplastics benefit bacteria colonization and induce microcystin degradation
Polystyrene microplastics in a microcosm experiment facilitated bacterial colonization and promoted the degradation of the cyanobacterial toxin microcystin, with the plastisphere community showing distinct metabolic activity compared to free-living bacteria. The study reveals that microplastic biofilms can unexpectedly accelerate detoxification of co-occurring harmful algal bloom toxins.
Interaction of cyanobacteria with calcium facilitates the sedimentation of microplastics in a eutrophic reservoir
Researchers found that cyanobacteria interactions with calcium facilitate the sedimentation of initially buoyant polyethylene microplastics in a eutrophic reservoir. Phototrophic sessile cyanobacteria precipitated calcite while forming biofilms on microplastic surfaces during summer, increasing particle density and driving their transfer to sediments.
Interaction of Cyanobacteria with Nanometer and Micron Sized Polystyrene Particles in Marine and Fresh Water
Marine and freshwater cyanobacteria formed aggregates with polystyrene nanoplastics held together by extracellular polymeric substances, causing the particles to sink, with larger and faster aggregation in saltwater. Microplastics produced different-shaped aggregates linked by a small number of particles, neither causing cell death, showing that cyanobacteria can alter nanoplastic fate and distribution in aquatic systems.
Ecological implications beyond the ecotoxicity of plastic debris on marine phytoplankton assemblage structure and functioning
PVC, polystyrene, and polyethylene microplastics and nanoplastics significantly reduced phytoplankton cell density, with polymer type being a key factor; given phytoplankton's role in atmospheric CO2 fixation, plastic pollution could potentially impact the marine carbon pump.
