【摘要】 微藻以其生长周期短、不占用农业耕地而被作为第三代生物柴油的首选原料,然而微藻培养密度偏低含油率不高是制约微藻生物柴油规模生产的主要因素。结合微藻培养的营养方式和培养系统,讨论了近年来提高微藻培养密度及油脂(主要为甘油三酯)含量的各种研究方法及成果,分析了微藻高产油率的培养模式,并就培养成本问题做了进一步探讨。最后总结了微藻生物柴油的发展方向,即在合适的培养系统下以太阳光为能源,充分利用废气、废液甚至废固培养微藻,提高藻油的生产率,从而降低生物柴油的生产成本,进而实现工业化生产。更多还原

【Abstract】 Microalgae has become one of the most potential raw materials for production of biodiesel due to its short growth cycle and low soil demand for its growth.However,production of biodiesel from microalgae has currently not been commercialized all over the world.The reason is mainly high production cost resulting from low cell density and lipid content of microalgae.The paper reviewed the recent advances on technology of micro-algal high-density culture and high-lipid（triglycerides）production,discussed the effects of culture methods,culture systems and photobioreactor styles on yield and cost of micro-algal biomass and lipid.Finally,the intensified microalgal culture modes using solar energy,CO₂ integrated with sugar wastes were introduced.The integrated technology will improve the yield of microalgal lipid,and reduce the cost of microalgal biodiesel production,and make the process to be more competitive.更多还原
