Bioaccumulation and toxicity of selenium compounds in the green alga Scenedesmus quadricauda

Popis výsledku v původním jazyce

Background: Selenium is a trace element performing important biological functions in many organisms including humans. It usually affects organisms in a strictly dosage dependent manner being essential at low and toxic at higher concentrations. The impactof selenium on mammalian and land plant cells has been quite extensively studied. Information about algal cells is rare despite of the fact that they could produce selenium enriched biomass for biotechnology purposes. Results: We studied the impact of selenium compounds on the green chlorococcal alga Scenedesmus quadricauda. Both the dose and chemical forms of Se were critical factors in the cellular response. Se toxicity increased in cultures grown under sulfur deficient conditions. We selected threestrains of Scenedesmus quadricauda specifically resistant to high concentrations of inorganic selenium added as selenite (Na2SeO3) strain SeIV, selenate (Na2SeO4) strain SeVI or both strain SeIV+VI.
