Microalgae have the potentials in production of energy and bioresources and in the fixation of carbon dioxide. The performance of these applications greatly depends on the development of culture system for microalgae. In this report, a survey of the development of microalgae culture techniques was presented. Production of biodiesel as a renewable fuel from microalgal oil is expected to reduce emission of carbon dioxide. Open cultivation systems such as open pond and raceway are suitable for the production of biodiesel. However, cost must be reduced by using microalgae with higher growth rate and higher oil content. Closed cultivation systems are suitable for the fixation of carbon dioxide from power plant due to the higher absorption rate in cultivation systems with high concentration of biomass. However, the scale of closed cultivation system is too small for industrial emission of carbon dioxide.
Supply of light and transport of carbon dioxide are two main factors responsible for the performance of a cultivation system. In order to obtain highest growth rate, light inhibition and light shading must be avoided. Integration of absorption process and cultivation system will increase the removal rate of carbon dioxide.
