Abstract
Numerous studies have examined the feasibility of using microalgae as a long-term source of biofuel. This helped us to determine how different amounts of phosphorus changed the growth of lipids in Scenedesmus subspicatus, a freshwater microalga. This study examined the effects of various phosphorus concentrations on the biochemical makeup of algae, particularly the production of proteins and carbohydrates. When there was insufficient phosphorus, the investigation observed a significant increase in lipids and productivity of S. subspicatus. Additionally, gas chromatography was used to examine the fatty acid profiles of the green algae thoroughly. When Scenedesmus species were tested at different cell densities, the highest amount of chlorophyll was found to be 0.89 mg/L. The amounts of fatty acids in algae grown with 0.4 and 0.04 P of phosphorus were strongly correlated, as shown by the Pearson linear correlation coefficients. Gas chromatography analysis revealed that the major saturated fatty acids were stearic acid (C18:0) and palmitic acid (C16:0). In addition, confirming the presence of several unsaturated fatty acids (C16:3, C18:1, C18:2, and C18:3) has helped us learn more about S. subspicatus’s complex lipid profile of S. subspicatus and how well it can be used to produce biofuels.
