The paper deals with experimental results of researches on the role of brown algae Cystoseira barbata polysuccharides (alginic acids, fucoidan and algulose) in Sr⁹⁰ extraction from sea water. Fucoidan removal from Cystoseira barbata was found to decrease the capacity of the latter for Sr⁹⁰ concentration from the environment. Fucoidan in Cystoseira may play the role not only as a Sr⁹⁰ concentrator, but also as a stimulator for its processes of fixation by alginic acids. In the process of the Cystoseira decomposition pH of its intracellular solutions was observed to increase 5,87 to 7,4. A decrease in the Sr⁹⁰ c.f. values in Cystoseira barbata during the decomposition and detritus formation is due to a change in alginic acids' sorption properties with the change in pH of intracellular solutions.
