Polish scientists lead pioneering research. They have isolated the DNA of the ‘golden algae’ toxins
23.08.2022
Researchers from the University of Gdańsk have isolated the DNA and RNA of prymnesins, namely the toxins produced by 'golden algae.' The researchers are currently developing a standard that will precisely determine these little-known ichthyotoxins. There are no research standards in this area in the European Union.
Precise analyses of the toxins produced by Primnesium parvum will enable researchers to understand the mechanism of action of these micro-organisms. It may also help to pinpoint the conditions that favour the release of Primnesiums, which pose a lethal threat to aquatic organisms with gills. Scientists worldwide can only specify the factors that potentially favour the 'golden algae' bloom.
In August this year, the presence of Primnesium parvum in the waters of the Oder River was found by researchers from the Institute of Inland Fisheries in Olsztyn. Their production of large quantities of ichthyotoxins was confirmed by research conducted by experts from the laboratory of the Gdansk Institute, followed by analyses from the laboratory of the University of Vienna, which currently has the most experience in Europe in studying 'golden algae'. The Austrian results were identical to the Polish findings.
The preliminary report of the Team for the Situation Arising on the Oder River set up by the Minister of Climate and Environment will be published by the end of September.
