and stress conditions such as deprivation of N or phosphate, which limit cell growth, also increase lipid underlying principle is that where there is insufficient N for protein content.” “The production necessary for growth, excess carbon from photosynthesis is channeled into storage molecules such as et al p6). These quotes piece together to modulate the idea of TAG’s..”(Scott how to manipulate triacylglycerides, so that they are more prominent in the cell. If you limit the amount of nutrients, nitrogen or phosphate then you allow for the cell to store the extra carbon from photosynthesis as triacylglycerides. It has been found that letting the algal cells simply deplete the amount of nutrients themselves will result in a higher yield of lipids. This opposed to not adding enough nitrogen to begin with which does not have as much lipid in the end product. Metabolic engineering of lipid production pathways is a new research being implemented to aid in the amount of triacylglycerides in the final product. The more you have in the final product the more biofuel you will be able to create with the species of algae you are using. Another way of increasing lipid yields is to manipulate what processes go on in the selected strain. By removing unnecessary processes/pathways to the survival and production of lipids, one can utilize the extra energy for the needed pathways. Conclusion Algae as a feasible biofuel are indeed so promising. Solar energy is utilized as allowed by biofuels. Thus, there is a limitless use of biofuels from algal growth that will harness energy from the sun and maximize it to save the natural reserves from extinction. Hence, a successful implementation of this project would mean immensely to a world that constantly evolves with technology. Future Work The Future of algae as a viable biofuel, at this time looks very promising. It is however, not without certain challenges. Companies such as Sapphire Energy, Origin Oil and Solazyme are investing heavily in the research and development of algae as a fuel source. Even the U.S. Government is experimenting with biofuels from renewable sources. President Obama, in a press release dated 30 March 2011 stated that the US Air Force has flown an F-22 Raptor using
