Description	We selected a strain of Scenedesmus quadricauda, which is able to grow fast even in the presence of high selenite concentration. Its biomass can serve as a source of selenomethionine in food and feed supplements. In this paper we present the results of two principally different analytical approaches: sequential fractionation and the alternative - HPLC connected with ICP-MS for the purpose of proper selenium species determination. The most important output is the amount of selenomethionine, but we also examined the content of selenomethionine-Se-oxide, selenite, and methylseleninic acid.
