Abstract
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.
Abstract (in Czech)
Vyselektovali jsme kmen Scenedesmus quadricauda, který je schopen rychle růst i za přítomnosti vysokých koncentrací seleničitanu. Jeho biomasa může sloužit jako zdroj selenometioninu ve výživových a krmivových doplňcích. V tomto příspěvku presentujeme výsledky dvou odlišných analytických přístupů: Sekvenční frakcionace a alternativy – HPLC spojené s ICP-MS za účelem rozlišení jednotlivých chemických forem selenu. Nejdůležitějším výstupem je obsah selenomethioninu, ale dále bylo zkoumáno i množství oxidovaného selenomethioninu, seleničitanu a methylseleničité kyseliny.
