Although the potential for biofuel production from microalgae via photosynthesis has been intensively investigated, information on the selection of a suitable operation strategy for microalgae-based biofuel production is lacking. Many published reports describe competitive strains and optimal culture conditions for use in biofuel production; however, the major impediment to further improvements is the absence of effective engineering strategies for microalgae cultivation and biofuel production. This comprehensive review discusses recent advances in understanding the effects of major environmental stresses and the characteristics of various engineering operation strategies on the production of biofuels (mainly biodiesel and bioethanol) using microalgae. The performances of microalgae-based biofuel-producing systems under various environmental stresses (i.e., irradiance, temperature, pH, nitrogen depletion, and salinity) and cultivation strategies (i.e., fed-batch, semi-continuous, continuous, two-stage, and salinity-gradient) are compared. The reasons for variations in performance and the underlying theories of the various production strategies are also critically discussed. The aim of this review is to provide useful information to facilitate development of innovative and feasible operation technologies for effectively increasing the commercial viability of microalgae-based biofuel production.
虽然通过光合作用从微藻中生产生物燃料的潜力已经得到了深入研究，但缺乏有关选择适合微藻生物燃料生产的操作策略的信息。许多已发表的报告描述了用于生物燃料生产的有竞争力的菌株和最佳培养条件；然而，进一步改进的主要障碍是缺乏用于微藻培养和生物燃料生产的有效工程策略。本综述讨论了最近在理解主要环境胁迫对生物燃料（主要是生物柴油和生物乙醇）生产的影响以及各种工程操作策略的特性方面的进展，这些策略是使用微藻进行生产的。比较了在各种环境胁迫（即光照、温度、pH 值、氮饥饿和盐度）和培养策略（即分批补料、半连续、连续、两阶段和盐度梯度）下基于微藻的生物燃料生产系统的性能。还批判性地讨论了性能变化的原因和各种生产策略的基础理论。本综述的目的是提供有用的信息，以促进开发创新和可行的操作技术，有效提高基于微藻的生物燃料生产的商业可行性。
