| Popis: | The Sea of Azov is a part of the Mediterranean basin and is the most continental sea in the world. But the phycological studies of the Sea of Azov were irregular. To assess the ecological safety of sea water, it is important not only to determine the presence of toxigenic species in the flora, but also to confirm the presence of strains capable of synthesizing toxins. The strain Nostoc linckia MZ–C21 was isolated from a planktonic sample collected near a seacoast of the Sivash (the bay of the Sea of Azov near Henichesk, Ukraine). PCR reactions demonstrated that the investigated strain has genes encoding all known groups of hepatotoxins: microcystin (the mcyE gene), nodularin (the ndaF gene), and cylindrospermopsin (the cyrB gene) synthetases. The novel strain MZ–C21 formed strongly supported phylogenetic lineages with other microcystin and nodularin producers. Thus, there is a high probability for the production of cyanotoxins by Nostoc linckia growths in the Sea of Azov near Henichesk. |
