Background and Objective: Due to the declining fossil fuel resources as well as the need for an alternative source of biodegradable source of energy, biodiesel has a great advantage over conventional fuel due to its low content of particulates. This study investigated the production and characterization of biofuels produced from the fresh water microalgae; Chlorella vulgaris. Materials and Methods: Water was sampled from Sharada industrial run-off within Kano metropolis for isolation and identification of algal species. Chlorella vulgaris was identified under a light microscope and isolated by repeated sub-culturing on BG-11 media. Scale-up of the culture was done using a designed photo-bioreactor for 23±2 days after which oil was extracted using solvent extraction method. This oil was converted to biodiesel through transesterification with KOH as a catalyst and the physico-chemical characterization of the fuel were achieved using special physico-chemical characterization methods to evaluate its quality. A FT-IR spectrum was used to determine if fatty acids were converted to fatty acid methyl esters. Results: Microalgal species isolated were; Spirogyra, Scenedesmus, Nitzschia, Anabaena, Chlamydomonas, Oscillatoria, Zygnema, Volvox and Chlorella sp. A 50 g of biomass of C. vulgaris produced almost 5.092 mL of oil in 3 weeks. The physico-chemical properties obtained were in line with the American Society for Testing Materials (ASTM) standard values. The biodiesel properties of the oil indicated that the biodiesel meets the ASTM standard. FT-IR spectra analysis revealed the peak of biodiesel production at 1745 C=O produced. Conclusion: So, it was concluded that the biofuel produced by Chlorella vulgaris biomass have excellent qualities suitable for use in the transport industry and therefore; it can be recommended for use as an economically viable source of renewable energy.
