Abstract (description)
The Black Sea brown alga Cystoseira barbata has been studied to determine stable and radioactive isotopes of chemical elements in its biochemical components. Results show different contents of stable and radioactive isotopes in the alga components. Under experimental conditions 40% of 54Mn, 25 % of 65Zn and 53 % of 60Co are not incorporated into structures extracted from the algae by alcohols of various concentrations (mannite, free a-amino acids, lipids, fucoidan). A significant role in Mg, Mn, Fe, Co, Ni, Zn, Cu and Pb uptake processes by Cystoseira is attributed to ionexchangable processes occurring in the system of sea-polysaccharides (alginic acids, fucoidan in the organism). Algulosa is insignificant for these processes. The Ca : Sr and Co : Ni ratios in the Cystoseira biochemical structures are of specific character.
