Abstract: The objective of this study was to investigate the accumulation of lipid, biomass, photosynthetic pigment, protein and carbohydrates from various micro algal strains. Algal cultures were grown in BG-11 medium inoculated into nitrogen (N) and phosphorus (P) en rich and stress medium. Three different treatments were set up- N+P+ (control group); (N-P+); (N+P-) respectively for algal growth evaluation in the form of lipid accumulation, biomass yield, protein, carbohydrate and total chlorophyll contents. When the cells were grown in BG-medium under nutrient stress (N,P) for 12 days, in (N+P+) nutrient regime, significant (P≤0.05) higher biomass yield 1.129±0.036 gL-1 and 1.115±0.021gL-1 have been reported in Nannochloropsis oculata, Chlorella pyrenoidosa respectively.
