We are in the process of selecting elite lines of Korean domestic microalgae for mass cultivation and biodiesel production in Korea. Twenty microalgal strains from various domestic streams and lakes were collected, axenically purified, and tested for physiological characteristics and lipid production. Many microalgae were able to autotrophically synthesize hydrocarbon chains such as pentadecane (C15H34) and heptadecane (C17H36), which can be directly used as fuel without requiring a transesterification step. Consequently, the genes involved in alkane biosynthesis such as an aldehyde decarbonylase and an acyl-acyl carrier protein (ACP) reductase were present in this microalgae. Genetic clonings and characterization of those domestic genes are currently underway. In addition, a high value fatty alcohol such as hexadecenol (C20H40O) was present in this photosynthetic microorganism. Other common algal biodiesel constituents, palmitic acid (C16:0), palmitoleic acid (C16:1), linoleic acid (C18:2) and linolenic acid (C18:3) were also produced by many strains as major fatty acids. Therefore, numerous domestic microalgae appear to show promise for their application in cost-effective production of microalgae-based biofuel and high-value products. Also we are investigating Korean type microalgae mass cultivation system to grow and induce lipids in various conditions. Over 100-ton raceways have been operated by our laboratory for field cultivation and currently approximately 1000-ton raceways are under construction. A few microalgal strains that are suitable for field mass-cultivation were selected.
