Abstract

Previous studies indicated that teratogenic polymethoxy-1-alkenes (PMAs) are produced by phylogenetically diverse cyanobacteria taxa, however corresponding studies on the occurrence of PMAs in European cyanobacteria are lacking. Herein, the presence of PMAs in strains of Raphidiopsis raciborskii and Aphanizomenon gracile isolated from surface waters in Poland was studied using nuclear magnetic resonance and mass spectrometry. No PMAs were detected in any of the strains investigated, indicating that production of these compounds may be geographically diversified. Further studies are necessary to elucidate mechanisms of cyanobacterial PMAs synthesis.
