Microalgae have been rising as a feedstock for biofuel in response to the energy crisis. Due to a high lipid content, composed of fatty acids favorable for the biodiesel production, microalgae are still being investigated as an alternative to biodiesel. Environmental factors and process conditions can alternate the quality and the quantity of lipid produced by microalgae, which can be critical for the overall production of biodiesel. To maximize both the lipid content and the biomass productivity, it is necessary to start with robust algal strains and optimal physio–chemical properties of the culture environment in combination with a novel culture system. These accumulative approaches for cost reduction can take algal process one step closer in achieving the economic feasibility.

为了应对能源危机，微藻作为生物燃料的原料一直在增长。由于高脂含量（由有利于生物柴油生产的脂肪酸组成），微藻仍在研究中，以作为生物柴油的替代品。环境因素和工艺条件可能会改变微藻产生的脂质的质量和数量，这对于生物柴油的整体生产至关重要。为了使脂质含量和生物质生产力最大化，有必要从稳健的藻类菌株和培养环境的最佳理化特性开始，结合新颖的培养系统。这些降低成本的累积方法可以使藻类生产过程在实现经济可行性方面更近一步。
