Algae Production For Biofuel - Article ExampleTraditional ethanol and inunct teeming plants such as sugarcane, corn and rapeseed have been tried successfully in various regions of the world to flag biodiesel for industrial use. However, the economics of biodiesel drudgery has still to provide figures for potentially practicable and sustainable way of life to this end. Algae, which atomic number 18 simple botanical forms of life possessing the ability to reproduce at a fast rate with token(prenominal) of inputs ar being looked at as a potential sources of biodiesel, as some of the millions of its species have been observed to be rich in triglycerides and other fats/oils necessary for biofuel production. The major advantage of using alga for biofuel production is that they age in ponds and waste pee, which do not encroach upon terrestrial territory already reserved for the finishing of food crops. Moreover, algae possess the ability to double their biomass in as less as oneness day under optimized conditions (Odlare et al, 2011). The towering growth rate however has to be optimized in relation to oil production within the organism as these two properties are contradictory to each other (Csavina et al, 2011). Methodologies and technologies are therefore being developed to cultivate algae in controlled conditions to achieve this objective. Lipids, sugar and hydrogen throttle are considered the primary units of energy and a study at the University of Arizona reveals that algae have a distinct advantage over terrestrial cultivable crops such as corn as they possess a 300 fold advantage in producing the basic units for producing biofuel (Littin, 2011). Although the cost of production of fuel from algae still exceeds the value of the final product, intensive research is going on at the university as tumesce as other parts of the world to optimize the process towards a profitable direction (Littin, 2011). Moreover, it has been observe that secondary w astewater rich in nitrogen and phosphorus can be utilized to grow algae eliminating the need of fertilizers (Littin, 2011). In turn, the algae besides producing lipids for potential use as biofuel purify the water as well, resulting in a double benefit. Grown in controlled conditions of specific light exposure and privation of nitrogen and sulfur at particular stages of their life promote lipid production in the algae, which are the strategies being explored by the scientists involved in this research (Littin, 2011). Biofuel or biodiesel can be produced from any biomass which has high lipid content. The process involves extraction of oil from the biomass by a process called transesterification which yields triglycerides, which possess the properties ideal for a biofuel (Taylor, 2011). Algae can either be grown in open ponds or in controlled conditions in what is known as a photo-bioreactor (Taylor, 2011). The latter is a sealed aquaculture system in which conditions can be optimize d and manipulated according to required objectives of high lipid production by the organisms. Such bioreactors are however high-priced to build as well as maintain and may not be the ideal means for biofuel production from algae. Identification of the appropriate species and varieties of algae growing in pictorial ponds and wastewater reservoirs in natural conditions, which provide the maximum yield of lipids can be the only means, once identified, to make economically feasible and sustainable methods for
