The Effect of Nutrient Concentration on the Standing Crop of Scenedesmus obliquus grown under Continuous Culture Condition

Abstract

The standing crop of Scenedesmus obliquus grown under continuous culture condition with a specific growth rate of about 1.0/day was determined for different concentrations of mineral nutrients. The concentrations of carbon, nitrogen and phosphorus to maintain chlorophyll a concentration at a level of 10μg/l that corresponds roughly to the minimum chlorophyll concentration in eutrophic lakes were suggested to be about 500, 100 and 2.5μg/l, respectively.
