微藻中油脂提取方法的研究现状及进展

Research status and advances in the methods of lipid extraction from microalgae

在世界能源危机的影响下,生物质能源由于具有可再生、低污染等优势,被认为是在未来一个较短时期内最有潜力缓解能源危机的石油替代品。而微藻由于具有生物量大、光合效率高、生长周期短、油脂含量高和环境友好等优点,有望破解后石油时代的能源危机。笔者介绍了国内外生物柴油的应用现状,阐述了微藻作为生物柴油原料的优势,并对近年国内外利用微藻提取油脂的诸多方法进行了详细介绍与比较。

Under the influence of the world＇s energy crisis, biomass energy is considered to be the petroleum replacement with the greatest poten- tial to alleviate the energy crisis in a relatively short period of time in the future due to the superiority of being renewable, low pollution, and so on. Because of the advantages of being large biomass, high photosynthetic efficiency, short growth cycle, high lipid content, environmental friendliness, and so on, microalgae is expected to break the energy crisis in the post - petroleum age. The author describes the application sta- tus of biadiesel at home and abroad, and expounds the advantages of microalgae as a biadlesel feedstock, and also describes and compares in detail the many methods for using microalgac to extract lipid at home and abroad in the near future.
