Algal process flow diagram with integrated industrial CO2 sequestration. 2.1 Commercial applicability of microalgal biofuels As the name microalgae suggests the relative size of these organisms may seem unsuitable for generating massive quantities of biofuel on a global scale nonetheless microalgae offer many advantageous qualities for biofuel production especially when compared to terrestrial bioenergy crops. The basic principle of generating biofuel from microalgae is to exploit these cells as biological factories whose lipid output can be as much as 70 of their total dry biomass under optimal conditions. While many species of algae exhibit the natural capacity to produce abundant amounts of oil for conversion to biofuel a major obstacle in the commercialization of such a process lies in the scalability. Many exciting breakthroughs in algal biotechnology have occurred on the lab bench but mass cultivation of algae is still associated with some of the most challenging problems. A few areas of intense research focus include highly productive growth systems temperature control photooxidative stress tolerance light intensity regulation harvesting and downstream processing. Whether it is through the manipulation of culture conditions or the application of mutagenesis and genetic engineering the biological networks of these unicellular creatures can potentially be optimized to synthesize and or secrete biofuel metabolites particularly in the form of lipids 272 Biofuel s Engineering Process Technology and other hydrocarbons in order to overcome some of the aforementioned stumbling blocks to large-scale cultivation. It is difficult to convey a concise list of the ideal species for biofuel production because the organism must be paired not only with the climate in which it will be cultivated but also the specific mechanism of cultivation and desired end products. Also the lipid
