In recent years, the not too distant exhaustion of fossil fuels is becoming apparent. Apart from this, the combustion of fossil fuels leads to environmental concerns, the emission of greenhouse gases and issues with global warming and health problems. Production of biodiesel from microalgae may represent an attractive solution to the above mentioned problems, and can offer a renewable source of fuel with fewer pollutants. This review presents a compilation of engineering challenges related to microalgae as a source of biodiesel. Advantages and current limitations for biodiesel production are discussed; some aspects of algae cells biology, with emphasis on cell wall composition, as it represents a barrier for fatty acid extraction and lipid droplets are also presented. In addition, recent advances in the different stages of the manufacturing process are included, starting from the strain selection and finishing in the processing of fatty acids into biodiesel.
近年来，化石燃料即将枯竭的情况日益明显。此外，化石燃料的燃烧还导致了环境问题、温室气体排放以及全球变暖和健康问题。利用微藻生产生物柴油可能是解决上述问题的一个有吸引力的方案，因为它可以提供一种污染物较少的可再生燃料。本综述介绍了与微藻作为生物柴油来源相关的工程挑战。讨论了生物柴油生产的优点和当前的局限性；还介绍了藻类细胞生物学的一些方面，重点是细胞壁的组成，因为细胞壁是脂肪酸提取和脂质滴的障碍。此外，还包括制造过程各个阶段的最新进展，从菌株选择到脂肪酸加工成生物柴油。
