微藻具有诸多优良特性,是生物柴油最具潜力的原料之一。但大规模培养微藻制备生物柴油尚需解决优良藻种的选育、高密度培养、细胞采收、脱水及高效生物反应器设计等技术问题。该文从藻种、营养因素、培养条件、营养方式及培养模式等方面,阐述了当前影响富油微藻高密度培养和油脂积累因素的研究概况,以期为微藻培养及微藻油脂生产研究者提供参考。

Microalgae is one of most attractive feedstock for biodiesel due to its lots of 1excellent properties. However,there were a variety of bottlenecks for large-scale cultivation of microalgae,e. g. breeding microalgal strains,high density cultivation technology,harvesting and dehydration of microalgal biomass,design of efficient bioreactor and so on. This review illustrates the factors in high-density cultivation and lipid accumulation of oleaginous microalgae to provide references for microalgal technologists,in terms of microalgal species,nutrient elements,culture conditions,nutrition styles and cultivation modes.
