Abstract
Samples of macrophyte algae were collected from an ecotope of Kandalaksha Gulf, the White Sea. These algae were selected from substrates, storm wracks and after long-term storage in the soil, and they were assessed by indirect competitive enzyme immunoassay for the presence of low-molecular-weight metabolites of micromycetes (mycotoxins). In Fucus distichus, F. serratus, F. vesiculosus, and Ascophyllum nodosum, the concentrations of all analyzed toxic substances from storm wracks were uniformly reduced compared to those in living thalli. For Laminaria digitata, Saccharina latissima, and Ahnfeltia plicata, in living individuals of which mycotoxins were not found or were extremely rare, cases of contamination with citrinin, mycophenolic acid, emodin and sterigmatocystin were found in storm wracks. After 12 months of burial in soil F. distichus samples had only 9 components out of 16 analyzed. In F. serratus, F. vesiculosus, A. nodosum, and Pelvetia canaliculata, only emodin, mycophenolic acid, alternariol, and ergot alkaloids were determined.
期刊介绍：
The Russian Journal of Marine Biology was founded in 1975 by Alexey V. Zhirmunsky, member of the Russian Academy of Sciences. The Russian Journal of Marine Biology covers a wide range of research and some applied aspects of marine biology as a synthetic science related to various fields of study on marine biota and environment. It presents fundamental research on biological processes at molecular, cellular, organismal, and populational levels in marine organisms. Consideration is given to marine objects as models in life sciences. The journal also publishes papers dedicated to events in Russian and international marine biological science and the history of biology.
