Abstract
Energy security is the most challenging task of 21st century. But this task needs to get addressed dynamically. There is a need of systematic investigation on potential sources of bio energy and enhancing their yield using scientific methods. This study aims at understanding the effect of Nitrogen supplementation on growth and biomass productivity of microalgae. The effect of Nitrogen supplementation on chlorophyll-a, lipid and carbohydrate content in microalgae consortium has been observed. The effect of two different nutrient media on biomass composition of microalgae consortium at optimized urea concentration has also been observed for 21 days in control, BG-11 and BBM media. The results indicate that at 0.1% Urea treatment the BBM media favours the micro-algal growth compared to the BG-11 media. But, in absence of Urea, the BG-11 media favours growth over BBM media at later stages. Highest value of Chlorophyll-a concentration was reported in T1 (0.1% Urea) followed by Control and T2 (0.5% Urea) on 21st day of cultures.
