The effect of salinity on the interaction between microplastic polyethylene terephthalate (PET) and microalgae Spirulina sp.
Researchers examined the interaction between PET microplastics and the microalga Spirulina under varying salinity conditions, finding that salinity influenced how microplastics affected algal growth and their potential to enter the food supplement chain.
The Effect of Mixed Microplastic on Freshwater Microalgae Growth and Survival
Researchers tested the effects of mixed polypropylene and PVC microplastics at five different ratio combinations on a freshwater microalgae community, finding that mixture composition affected algal growth and survival differently than either polymer alone.
Interaction between polyethylene terephthalate (PET) microplastic and microalgae (Scenedesmus spp.): Effect on the growth, chlorophyll content, and hetero-aggregation
Researchers exposed two types of freshwater microalgae to PET microplastics at various concentrations, finding that higher levels significantly stunted growth, reduced chlorophyll, and caused the algae to cluster around the plastic particles. This "hetero-aggregation" behavior suggests microplastics can physically trap microalgae, potentially disrupting aquatic food webs that depend on algae as a foundation.
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.

Determination of polyethylene microplastics toxicity by microalgae Scenedesmus sp.
This study investigated the toxicity of polyethylene microplastics on the freshwater microalgae Scenedesmus sp. Results showed that microplastics inhibited algal growth and photosynthesis, indicating potential harm to aquatic ecosystems.
Impacts of polyethylene microplastics on the microalga, Spirulina (Arthrospira platensis)
This study examined how polyethylene microplastics affect Spirulina, a widely cultivated blue-green algae used in food and supplements. Researchers found that at higher concentrations, microplastics reduced Spirulina growth and caused oxidative stress, while the algae also physically entangled with the plastic particles. The findings suggest that microplastic contamination could threaten both natural algal ecosystems and the commercial production of this important food source.
Toxic Effects of Microplastics on Culture Scenedesmus quadricauda: Interactions between Microplastics and Algae
Researchers found that microplastics from multiple polymer types inhibit growth of the freshwater alga Scenedesmus quadricauda and induce oxidative stress, with toxicity varying by polymer type, particle size, and concentration.
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.
Effects of biofouled plastics on phytoplankton community assembling and water chemistry: pilot study and implications for freshwater environments
Researchers conducted a pilot laboratory study exposing a five-species freshwater phytoplankton community to pristine and biofouled polypropylene fragments to investigate whether plastic acts as a carrier for algal species dispersal and to assess effects on water biodiversity and chemistry in freshwater environments.
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.
Effects of polyethylene terephthalate microplastics on cell growth, intracellular products and oxidative stress of Scenedesmus sp.
Researchers exposed freshwater microalgae to PET microplastics, a common plastic found in beverage bottles and textiles. Higher concentrations of PET particles significantly reduced algal growth and disrupted the cells' internal production of lipids, carbohydrates, and proteins. The study suggests that PET microplastic pollution in wastewater could harm the tiny organisms that form the foundation of aquatic food webs.
Micro/nano-plastics and microalgae in aquatic environment: Influence factor, interaction, and molecular mechanisms.
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.
Effect of microplastics exposure on the photosynthesis system of freshwater algae
Researchers investigated how polypropylene and polyvinyl chloride microplastics affect the photosynthesis system of freshwater algae and found that both types reduced chlorophyll content and impaired photosynthetic efficiency. The damage was concentration-dependent and worsened over the growth period. The study highlights that microplastic pollution in freshwater can harm algae, which form the base of aquatic food chains.
Plastic habitats: Algal biofilms on photic and aphotic plastics
Researchers tracked algae colonizing plastic surfaces in a freshwater reservoir over six weeks, finding that different plastic types developed distinct algae communities and that plastic surfaces showed early signs of degradation — suggesting that biofouling may accelerate microplastic fragmentation in freshwater systems.
Different interaction performance between microplastics and microalgae: The bio-elimination potential of Chlorella sp. L38 and Phaeodactylum tricornutum MASCC-0025
Researchers investigated how two species of microalgae, Chlorella and Phaeodactylum tricornutum, interact with common microplastic types including polypropylene, polyethylene, PET, and PVC. The study found that these microalgae have different capacities to interact with and potentially help remove microplastics, suggesting a possible green and cost-effective approach to microplastic bio-elimination from contaminated waters.

Application of freshwater microalgae Scenedesmus sp. for determining the toxicity of polypropylene microplastic particles
Polypropylene microplastics were found to be toxic to the freshwater microalgae Scenedesmus sp. in a dose-dependent manner. Since microalgae form the base of aquatic food chains, their sensitivity to microplastic exposure has cascading implications for freshwater ecosystems.
Toward a better understanding of microalgal photosynthesis in medium polluted with microplastics: a study of the radiative properties of microplastic particles
This study measured how microplastic particles from two common polymers — polyethylene terephthalate (PET) and polypropylene (PP) — interact with light, finding that both scatter light strongly rather than absorbing it. This matters because microplastics floating in waterways can shade out microalgae by blocking light needed for photosynthesis, potentially disrupting aquatic food webs at their base.
