Abstract
Biodiesel is a renewable, completely burning, non-toxic and eco-friendly fuel commonly derived from microalgal lipid. The present study aimed to isolate mutated strains of Dictyosphaerium ehrenbergianum (M-DE) and evaluated its enhanced lipid production and biodiesel efficiency. The mutagen ethyl methane-sulfonate (EMS) was used to induce mutation. The M-DE was mass cultivated in a bioreactor, and its fatty acid profile was analyzed using gas chromatography-mass spectroscopy (GC-MS). The total cytosolic lipid content was increased compared to the unmutated strain of D. ehrenbergianum (U-DE). In GC-MS analysis, a total of fifteen different fatty acids were identified from the lipid of M-DE, among which palmitic acid was recorded as a major fatty acid. The kinematic viscosity, flashpoint, density at 15°C, ash contents, and an acid number of M-DE were comparable with the recommended values of Indian and US petroleum, petroleum products, and lubricants sectional committee. The obtained results confirm that M-DE could be used as an efficient alternative source for the production of biodiesel on large scale.
