Microbiome, mixotrophic algae, zooplankton, and fish amino acid and phospholipid fatty acid content in terrestrial and plastic carbon treatments

<p>Data includes amino acid (&micro;g AA mg DW^-1) and phospholipid fatty acid content (&micro;g FA mg DW^-1) of the microbiome, mixotrophic algae, zooplankton, and fish<em> </em>from the four-trophic level experiment.&nbsp;The experiment included control (no addition), 13.5% ¹³C-labelled beech leaves (<em>Fagus sylvatica</em>), 97% ¹³C-labelled lignin-hemicellulose extracted from wheat (<em>Triticum aestivum</em>, ~80% lignin, 13% hemicellulose), and 99% ¹³C-labelled polystyrene (microplastic).&nbsp;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 (<em>Cryptomonas </em>sp.) was introduced to the bottles.&nbsp;In the next step, herbivorous zooplankton (<em>Daphnia magna</em>) consumed microbes, mixotrophic algae, and particles for five days which after they were used as the diet to zebrafish (<em>Danio rerio</em>) during a five-day experiment.</p>
