Microbiome, mixotrophic algae, zooplankton, and fish amino acid and phospholipid fatty acid content in terrestrial and plastic carbon treatments
Summary
This duplicate dataset entry contains nutritional composition measurements from an aquatic food web experiment examining how plastic-derived carbon compares to natural leaf litter as an energy source across trophic levels. The study provides direct evidence of how microplastic carbon is incorporated into the food web.
Data includes amino acid (µg AA mg DW-1) and phospholipid fatty acid content (µg FA mg DW-1) of the microbiome, mixotrophic algae, zooplankton, and fish from the four-trophic level experiment. The experiment included control (no addition), 13.5% 13C-labelled beech leaves (Fagus sylvatica), 97% 13C-labelled lignin-hemicellulose extracted from wheat (Triticum aestivum, ~80% lignin, 13% hemicellulose), and 99% 13C-labelled polystyrene (microplastic). Incubation time in humic lake water was 14 days in the control, leaf, and lignin experiment but 56 days for polystyrene, which after mixotrophic algae (Cryptomonas sp.) was introduced to the bottles. In the next step, herbivorous zooplankton (Daphnia magna) consumed microbes, mixotrophic algae, and particles for five days which after they were used as the diet to zebrafish (Danio rerio) during a five-day experiment.

Microbiome, mixotrophic algae, zooplankton, and fish amino acid and phospholipid fatty acid content in terrestrial and plastic carbon treatments
This dataset contains amino acid and fatty acid composition data from a four-trophic-level aquatic food web experiment that included plastic carbon as a treatment. The data supports research on how plastic carbon enters and moves through aquatic food webs from microbes to fish.
The second life of terrestrial and plastic carbon as nutritionally valuable food for aquatic consumers
Researchers used carbon-13-labeled experiments to trace how terrestrial leaves, lignin, and polystyrene microplastics are processed through a four-level aquatic food web from microbes to fish. While microbes could synthesize amino acids and lipids from plant-derived carbon, they produced far fewer nutritional biomolecules from polystyrene, and the resulting molecules were still incorporated into zooplankton and fish tissues. The study shows that plastic carbon can move through food webs and become part of animal body tissues, though at reduced nutritional value, raising concerns about the long-term health of aquatic ecosystems and the quality of fish consumed by humans.
What do microplastics mean for aquatic food webs? Some insight from ongoing experimental work in a freshwater ecosystem laboratory.
Researchers used large in-lake mesocosm experiments to investigate whether microplastic exposure altered essential fatty acid composition in yellow perch and zooplankton in a freshwater food web. Fatty acid composition was unaffected when supplemental food was provided, but preliminary results suggested lower fish body weight at high MP concentrations (29,240 particles/L) without supplemental feeding, indicating food dilution as a potential mechanism of MP impact.
Increasing microplastic exposure had minimal effects on fatty acid composition in zooplankton and yellow perch in a large, in-lake mesocosm experiment
Researchers found that increasing microplastic exposure levels had minimal effects on fatty acid composition in an aquatic organism, suggesting that at the tested concentrations, microplastics do not substantially disrupt lipid metabolism.
Polystyrene microplastics exposure modulated the content and the profile of fatty acids in the Cladoceran Daphnia magna
Researchers exposed Daphnia magna to polystyrene microplastics for 21 days and found that fatty acid content and composition were significantly altered. The changes suggest microplastics interfere with energy allocation in this freshwater crustacean, with effects varying by particle size and concentration.
