Abstract :Selenium is an essential element for all living organisms. Since its deficiency can cause health problems, it is supplied from the outside during nutrition through foods or supplements. Microalgae have become vector organisms among aquatic organisms during their transportation to the final consumer human in the food chain. However, selenium is an important supplement that should be consumed in sufficient proportions, and since its consumption at high levels will create a toxic effect, the doses to be provided must be consumed by considering factors such as age and gender. The upper selenium concentration is toxic for microalgae culture. For this reason, the effect of adding selenomethionine at 50, 75, 100 and 250 mg/L concentrations in the culture medium of Scenedesmus quadricauda on microalgae growth and chlorophyll-a content was investigated. According to the results obtained that the highest chlorophyll-a and cell number were measured as 0.593±0,1µg/L and 64±4,9 x106cells/mL using 50 mg/L selenomethionine in the culture. It has been detected the highest selenomethionine concentrations caused toxic for Scenedesmus quadricauda culture.
