| Popis: | International audience; As a result of eutrophication among other factors, bloom forming species of cyanobacteria frequently thrive and dominate communities in freshwater ecosystems. Cyanobacteria are considered as a nuisance and hazardous due to the production of toxins. The most potent and studied cyanobacterial toxins are the microcystins, especially the variant microcystin-LR (MC-LR). Daphnia magna plays a central role in freshwater pelagic food webs and its populations are negatively affected by cyanobacteria due to nutritional inadequacy, feeding interference and toxic effects on growth and reproduction. Biotransformation and antioxidant enzymes, amongst others enable D. magna capacity to cope with MC-LR up to a certain concentration. Aim of our study was to investigate the age related acute effects of MC-LR on D. magna biotransformation and antioxidant enzymes (glutathione S-transferase, GST and catalase, CAT), subsequent lipid peroxidation and furthermore to lactate and the enzyme lactate dehydrogenase (LDH).
