Cylindrospermopsin (CYN) is an alkaloid type cytotoxic metabolite produced by several cyanobacterial species, which caused human illnesses. The occurrence of CYN has been mostly associated with tropical and subtropical cyanobacteria, but recently it is appearing in several countries, all over the world. We analyzed CYN concentration and polyketide synthase/peptide synthetase (PKS/PS) genes, important parts of the gene cluster responsible for the CYN biosynthesis, in 14 isolated/collected Cylindrospermopsis raciborskii and Aphanizomenon ovalisporum strains originated mostly from Hungary. CYN and PKS /PS genes were detected in Aphanizomenon ovalisporum strains isolated from Spain (of our isolation) and isolated in Israel (ILC-164), but the Hungarian isolate from the hyposaline Lake Szelidi had a lack of production capacity. In the Hungarian samples of C. raciborskii, we found no CYN and PKS/PS genes content comparing to CYN producer C. raciborskii AQS originated from Australia.
