Abstract
Biofuels have become a renewable energy because the oil price fluctuates depending on global major events such as Iran-Iraq War, financial crisis. World carbon dioxide emissions from burning fossil fuels have surged to record levels. Microalgae, one of the feedstock of biodiesel, have a relatively faster growth rate than land plants and a higher lipid contents under proper condition. Moreover, microalgae are non-edible feedstock and do not require as large space for culture as other oil crops. However, the production costs of biodiesel from microalgae are higher than those of conventional petroleum diesel. It is necessary that biomass production has to be enhanced and optimized in order to reduce the production costs. Furthermore, to increase biomass production, it is more efficient to use microalgae which have faster growth rates than to use microalgae which are contained a lot of lipid contents. These studies were carried out in order to investigate significant factors for enhanceme
