Abstract:
The influence of different nitrogen source of varying concentrations on biomass production of green algae Scenedesmus was investigated. The result revealed that there was a significant difference among nitrogen sources in promoting algal biomass growth at lower concentrations of 5 and 10 mM. Nitrate was found to be a preferred form of nitrogen source and potassium (0.32 g/L) and sodium nitrates (0.28 g/L) performed better for biomass growth of Scenedesmus. Among the ammonical forms, urea (0.25 g/L) resulted in almost equal biomass as nitrates, making it an economical substitute for nitrogen source in large scale culturing of algae being commercially available.
