| Abstract | Industrial waste molasses is one of the major soil pollutants. This waste increasingly affects land fertility, human health, and the environment. Hence, this study proposes an efficient method for the disposal of sugar cane residue and reutilization of value-added components from molasses juice. Algal strains (Oedogonium sp., Ulothrix sp., Cladophora sp., and Spirogyra sp.) are grown in several molasses concentrations. Their subsequent effect of molasses on algal growth, metabolite accumulation, lipid profiling, and biodiesel production are investigated for the first time. It was noticed that 0.5% molasses increase biomass production of all algal species. Compared to the control, the highest accumulation was 38% in Oedogonium sp. and 46% in Ulothrix sp. after 5 days. Total chlorophyll, carbohydrates, and protein were also increased in all species. Similarly, lipid content was increased from 21–43%, with suitable changes in the fatty acid profile C16 to C18 as a prerequisite for optimum biodiesel production. The efficacy of biodiesel was further verified by the biodiesel standards such as EN 14,214 and ASTM D6751 iodine value, saponification, cetane number, cold filter plugging point, density, kinematic viscosity, oxidative stability, long-chain saturation factor, and higher heating value are in the range of standards; all of these fuel properties were significantly improved in the molasses media. Molasses can stimulate algal species growth and metabolites synthesis, which ultimately produce higher lipid yield and better biofuel quality and quantity.
