For achieving biodiesel production from microalgae, high density cultivation of microalgae is the most important step through the whole process. So, economical cultivation technology of microalgae should be developed.Photosynthetic mechanism consists of light reaction and dark reaction. In light reaction, light energy is converted into chemical energy in the form of the energy-carriers ATP and NADPH and in dark reaction, CO2 and water are converted into organic compounds.
Because dark reaction is considered as an overall rate-determining step in photosynthesis, it doesn’t need to illuminate photobioreactor (PBR) continuously by artificial light source. High microalgal growth rate can be achieved economically by development of PBR with periodic light having optimum duty cycle, not continuous light.In this study, optimum microalgal culture conditions in bubble column type PBR such as CO2 concentration, flow rate and medium were investigated. Based on optimum culture conditions, periodic light supply PBR of which duty cycle can be controlled in minutes or seconds was developed and microalgal productivity and celluar component by various duty cycles of periodic light were investigated.
