Strain Selection and Lipid Characterization of Marine Diatoms with Potential for Biodiesel Production
Phytoplankton is photosynthetic organisms that convert sunlight, water, and carbon dioxide into sugars, from which biological macromolecule, such as lipids, can be obtained. Due to their higher photosynthetic efficiency, higher biomass production, and faster growth rate, they have been suggested as very good candidates for biofuel production. High lipid content and fast growth rate are the major criteria for good candidate algal strains. Also, the algae should not be too difficult to harvest and must have a suitable and cost-effective cultivation system. Microalgae, like any other living organism, synthesize lipids which they use to maintain the integrity of their cells. Under specific circumstances, microalgae accumulate high concentrations of carbon in the form of TAG (Converti et al. 2009; Li et al. 2008; Liang et al. 2006; Melis and Mitra 2008).
