Abstract

Nowadays researchers are nominating microalgae for efficient treatment of effluents as well as producing plenty number of value added products by the same. This paper deals with the development of low cost culture medium using rice mill effluent (RME) for culturing fresh water microalga Scenedesmus pecsensis for valuable biomass production. The present study also examined the excessive nutrients removal from the RME. The experiments have been made to investigate the biomass production and nutrient consumption ability of S. pecsensis in RME using two different samples such as raw and autoclaved with help of cultivation. The highest phosphate (68.12%) and nitrogen (49.32%) elimination were observed with highest growth (0.956abs) and biomass production (5.27 g L−1) in autoclaved RME. While using commercial low cost fertilizers for biochemical production, the highest protein (472 mg G−1 DW) and carbohydrate (223 mg G−1 DW) yield was provided by Urea + Autoclaved RME.
