title: Domoic Acid in Cultures of the Diatom Genus Pseudo-nitzschia H. Peragallo in H. Peragallo &amp; M. Peragallo, 1900 and in Bivalve Samples from the Russian Waters of the Sea of Japan and the Pacific Waters of Kamchatka
abstract: Abstract The content of a dangerous amnesic toxin, that is, domoic acid (DA), was determined in cultures of the diatom genus Pseudo-nitzschia and in bivalve samples collected in the Russian waters of the Sea of Japan and off the Pacific coast of Kamchatka. For the first time, the presence of DA has been confirmed in cultures of Pseudo-nitzschia pungens (Grunow ex Cleve) G.R.
