Recently, bio-fuels receive extensive attention as a renewable and environmentally friendly alternative energy source due to the global issues of both greenhouse effects and conventional fossil fuels shortage. Microalgae, with the merits of environmental adaptability, high photosynthetic efficiency, neutral net carbon value and high lipid content, has become one of the most important raw materials for bio-fuels production, especially for the biodiesel production. In this paper, the advances of technology in microalgal culture with high lipid content are reviewed worldwide. The selection of high-lipid microalgae species, high-density culture of high-lipid microalgae and approaches to increase both the microalgal lipid content and the lipid production rate are discussed. The feasibility of microalgal lipid metabolism regulated by genetic engineering technology is elaborated. The intensified microalgal culture modes using the membrane bioreactor integrated with CO(2) exhaust gas as the carbon source are introduced. The integrated technology will further reduce the cost for microalgal lipid production whilst making this process to be economical for the production of biodiesel.
