Description	Green chlorococcal alga Scenedesmus quadricauda was found to be suitable to produce biomass with high content of organically bound selenium. We used a range of concentrations (10-400 mikrog/L) of selenium (added as Na2SeO3) to test its toxicity. We determined the concentration of 100 mikrog/L of selenium to be lethal for the wild type of S. quadricauda. We selected a strain able to grow well in the presence of selenium concentration up to 400 mikrog/L.
