RESUMO

Data on the accumulation and influence of selenium compounds on the vital activity of marine and freshwater algae are analyzed in the paper. Results of the study are indicative of a possibility of accumulation of large amounts of selenium (≤ 1000 times higher than its content in the aquatic environment) by microalgae. This element was registered in the composition of intracellular metabolites and high molecular compounds, primarily − amino acids, mono-, amino-, and polysaccharides, cytosol proteins and cell membranes, some fatty acids, and lipids. The process of accumulation is considered as the mechanism of detoxification and adaptation to a rather high content of selenium in the environment, and also as a way of selenium storage in algal cells.
