        abstract = {The increasing global demand for sustainable energy has directed attention toward third-generation biofuels derived from cyanobacteria. This study evaluated the biofuel potential and pigment profiling of three cyanobacterial strains-Nostoc punctiforme, Nostoc sp., and Anabaena sp.-isolated from freshwater sources in Tamil Nadu, India. Morphological identification confirmed strain-level differences, and pigment analyses revealed Nostoc sp. exhibited the highest chlorophyll-a (18.34 µg/mL) and phycobiliprotein content, indicating superior light-harvesting capacity. Conversely, Nostoc punctiforme showed the highest carotenoid content (0.0032 µg/mL), suggesting strong photoprotective traits. Lipid extraction using the Bligh and Dyer method identified Anabaena sp. as the top lipid producer (4.0% dry weight). Gas chromatography of fatty acid methyl esters (FAMEs) revealed a rich profile of medium- to long-chain fatty acids in Anabaena sp., including C16:0, C18:2, and C18:3, with significant concentrations of polyunsaturated fatty acids. These findings highlight the dual potential of freshwater cyanobacteria in sustainable biofuel production and high-value pigment applications, emphasizing their role as promising feedstocks for renewable energy and biotechnology.},
