Effect of microplastics on growth and biochemical composition of microalga Acutodesmus obliquus

Effects of Microplastic on the Growth and Nutrient Absorption of Microalgae

Physiological, morphological, and growth effects of microplastics on freshwater alga Chlorella vulgaris

AI summary · Read the abstract

Researchers showed that microplastics inhibit growth, reduce chlorophyll and photosynthetic efficiency, and trigger oxidative stress in the freshwater alga Chlorella vulgaris in a concentration-dependent manner, suggesting the species could serve as a bioindicator for aquatic microplastic contamination.

Dramatic Repercussion of Microplastics on Algae’s Population: Special Highlights on Nutraceutical and Active Ingredients Content

AI summary · Read the abstract

Researchers found that microplastics cause significant harm to algae, the first organisms they encounter in marine environments, potentially disrupting the nutritional and active compounds these algae produce, which could have ripple effects up the food chain and on industries that rely on algae for nutraceuticals.

Evidence that microplastics at environmentally relevant concentration and size interfere with energy metabolism of microalgal community

A short-term preliminary experimental study on the effect of microplastics on Chlorella vulgaris and duckweeds

AI summary · Read the abstract

Researchers exposed freshwater algae and duckweed — both important food sources for fish and humans — to microplastics and found that even small amounts inhibited growth and reduced photosynthetic pigments. This suggests that microplastic contamination in water could disrupt the base of aquatic food chains that people depend on.
