碩士 / 大葉大學 / 工學院碩士在職專班 / 102 / The massive use of fossil fuel results in the decrease of energy resources, the increase in oil prices and the serious release of greenhouse gases into the atmosphere. Microalgal biomass contains high-valued components, such as lipid, carbohydrates, polyunsaturated fat and carotenoids. Neutral lipid and carbohydrates can be transformed into biofuels such as biodiesel and bio-alcohol as substitutes for gasoline and diesel. Also with biomass, we can develop medical as well as health products. Therefore, cultivation of microalgae for biomass is considered as the most efficiently platform for the absorption and recycle of CO2.
The commercialized system for producing microalgae is more likely to use open type cultured system, although closed type system provides better pollution control and mass transportation efficiency. The major factors that have a giant impact on microalgae cultivation system are the CO2 transportation and the light supply. Most of the photobioreactors are sparged with air containing CO2. The rate of CO2 transported into culture is always far more than the need for the microalga growth. The efficiency of CO2 absorption is extremely low. Light supply has to avoid light inhibitory effect and the frond shadowing effect. Choosing or developing an appropriate microalgae cultivation system is raise the biomass productive efficiency and economic benefit.
