Bioenergy production from microalgae that is able to convert solar energy into biochemicals by photosynthesis is a realistic and possible way to replace diminished fossil fuels reservation such as coal, petroleum, others derived from petroleum. However, relatively high cost of production is a major obstacle prohibiting its commercialization. To cultivate mciroalgae using the nutrients dissolved in the seawater without any additional nutrients, semi-permeable membrane photobioreactor was developed for economical and eco-friendly production of microalgal bioenergy. Two major nutrients (N, P) for microalgal growth transfer rate across semi-permeable membranes were measured as function of different N, P concentration in artificial seawater. Then, microalgae were cultured using the semi-permeable membranes which have different molecular weight cut off(MWCO). Time profiles of algal biomass were increased with in proportion to nutrients transfer rate measured. Fatty acid methyl ester were analyzed and compared in all cases.
