Abstract

Biofuels is a substitute fuel for conventional biofuels that is made from vegetables oils, animal fats, and waste cooking oils. This paper discusses the possible environmental impacts and monetary feasibility of producing biofuels from algae grown in ponds. The fabrication of algal biofuels from Dunaliella tertiolecta, Nannochloropsis oculata, wild freshwater algae, and algae lipids using a highly efficient continuous catalytic process. Microalgae are the fastest-growing plants in the world. Manufacturing reactors for micro algal culture are open ponds, photobioreactors and closed systems. Microalgae are very important as a biomass source. Microalgae will some day be competitive as a source for biofuel. Algae have been recognised as a potential biofuels feedstock due to their high lipid efficiency and potential for cultivation on marginal land. Single-step procedure can potentially be a resource full of energy and an economical route for micro algal biofuels production. The lipid composition of the different microalgae was studied gravimetrically and by gas chromatography. Superior light intensity and exogenous CO2 concentration with longer lighting period encourage biomass accumulation, biofuels production, as well as the removal of chemical oxygen demand and nitrogen, while, lower exogenous CO2 concentration promotes phosphorus removal.
