Environmentally friendly biofuels are currently produced in large quantities using algal lipids. Objective: To perform mixotrophic cultivation of Chlorella vulgaris on Banana Waste for Biodiesel Production. Methods: Banana waste was treated with acid/alkaline, ground, and sun dried. The resultant hydrolysate was used into studies comparing photoautotrophic and mixotrophic conditions in microalgae culture. When biomass productivity and lipid content were measured. For mono-unsaturated, poly-unsaturated, and saturated forms, the lipid content differed. The research used analytical methods for fatty acid methyl ester analysis, such as GC-MS. Results: Mixotrophic cultivation exhibited a much higher biomass productivity (135 mg L-1 d-1) than photoautotrophic cultivation (115 mg L-1 d-1). Additionally, mixotrophically raised biomass had a much larger (w/w) lipid content (45%) than photo-autotrophically raised biomass (30 %). Higher amount of polyunsaturated fatty acids (palmitic and oleic acids) was shown by Lipidome. Conclusions: High-quality biofuel might be made possible by the regular availability of polyunsaturated fatty acids (64 mg g-1 of dry biomass) in the lipid contents of mixotrophically produced algal biomass
