The world energy system faces two major challenges: the requirement for more energy and less carbon. It is important to address biofuels production as an alternative to the usage of fossil fuel by utilizing microalgae as the potential feedstock. Yet, the commercialization of microalgae remains contentious caused by factors relating to the life cycle assessment and feasibility of microalgae-based biofuels. This present review starts with an introduction to the benefits of microalgae, followed by intensive elaboration on microalgae cultivation parameters. Subsequently, the fundamental principle along with the advantages and disadvantages of various pretreatment techniques of microalgae were reviewed. In addition, the conventional and recent advances in lipid extraction techniques from microalgae were comprehensively evaluated. Comparative analysis regard to the gaps from previous studies was discussed point-by-point in each section. The effort presented in this review will provide an insight for future researches dealing with microalgae-biofuel production on downstream processing.
对更多能源和更少碳排放的需求。利用微藻作为潜在原料生产生物燃料是替代化石燃料的一种重要方式。然而，由于与生命周期评估和微藻生物燃料可行性相关的因素，微藻的商业化仍然存在争议。本综述首先介绍了微藻的益处，然后详细阐述了微藻培养参数。随后，综述了各种微藻预处理技术的基本原理、优缺点。此外，还综合评价了微藻中脂质提取技术的常规和最新进展。在每一节中，都对点对点地讨论了与以前研究的差距的比较分析。本综述的研究工作将为今后从事微藻-生物燃料生产下游加工的研究提供参考。
