Effects Of Nitrogen Concentrations On The Biomass, Lipid And Biodiesel Production Potentials Of Spirogyra Specie
The international dependence on non-renewable power supply including fossil fuels has led the sector toward power insecurity. This has necessitated the worldwide attempt to reduce the dependence on fossil fuels and broaden an economically feasible and scalable alternative fuel supply so that it will additionally lessen huge emissions of CO2 within side the surroundings which in flip will result in discount environmental pollution. Biofuels have the potentials to offer a feasible opportunity to fossil fuels and can lessen overall CO2 emissions. Algae appear like a rising supply of biomass for biodiesel that has the capacity to absolutely displace fossil fuel. Biodiesel has gain sufficient interest in latest years because of its green nature, non-poisonous characteristics, biodegradability and decrease net carbon cycle as compared to standard diesel fuel. In this research, Spirogyra sp. was collected from Tubu river, a tributary of River Kaduna, as a source of biomass feedstock for biodiesel production. Spirogyra sp. turned into cultured in various nitrogen (2.94 x 103 (100%), 2.20 x 103 (75%), 1.47 x 103 (50%), 0.73 x 104 (25%), and 0.000 (0%)) concentrations in Bold’s Basal Media (BBM) in a laboratory test for 21 days at 25-28°C ambient temperature. Oil from Spirogyra sp. become extracted in soxhlet extractor using n-hexane as solvent and transformed into biodiesel through transesterification reaction. The highest biomass growth, oil, lipid content and biodiesel production were observed in treatment with 75% (2.20 x 103) Spirogyra sp. has a big capability for biodiesel production.
