Variability of cyanobacterial toxins in eutrophic pond (Hungary) Andrea Zsuzsanna Újvárosi Abstract: Various toxic metabolites can be produced by Cyanobacteria, which appear as water blooms in many eutrophic fresh water ponds in Hungary. Our purpose is observing toxic metabolites produced by Cyanobacteria at Pond Bárdos, Gyula. It has been three years since we started to determine the species, the gene clusters, structures of the toxic compounds as well as the concentration and toxicity of these metabolites. The results showed that the production of microcystin is cau­sed by Microcystis aeruginosa. Keywords: Cyanobacteria, water blooms, Microcystis aeruginosa, microcystin.
