Microalgae have the ability to mitigate CO(2) emission and produce oil with a high productivity, thereby having the potential for applications in producing the third-generation of biofuels. The key technologies for producing microalgal biofuels include identification of preferable culture conditions for high oil productivity, development of effective and economical microalgae cultivation systems, as well as separation and harvesting of microalgal biomass and oil. This review presents recent advances in microalgal cultivation, photobioreactor design, and harvesting technologies with a focus on microalgal oil (mainly triglycerides) production. The effects of different microalgal metabolisms (i.e., phototrophic, heterotrophic, mixotrophic, and photoheterotrophic growth), cultivation systems (emphasizing the effect of light sources), and biomass harvesting methods (chemical/physical methods) on microalgal biomass and oil production are compared and critically discussed. This review aims to provide useful information to help future development of efficient and commercially viable technology for microalgae-based biodiesel production.
微藻具有减少 CO(2)排放和生产高生产力油脂的能力，因此具有在生产第三代生物燃料方面的应用潜力。生产微藻生物燃料的关键技术包括确定高产油的理想培养条件、开发有效和经济的微藻培养系统，以及微藻生物质和油的分离和收获。本综述重点介绍了微藻培养、光生物反应器设计和收获技术的最新进展，主要关注微藻油（主要是三酰基甘油）的生产。比较和批判性讨论了不同微藻代谢（即光养、异养、混养和光异养生长）、培养系统（强调光源的影响）和生物质收获方法（化学/物理方法）对微藻生物量和油脂生产的影响。本综述旨在提供有用的信息，帮助未来开发高效和具有商业可行性的基于微藻的生物柴油生产技术。
