The potential for biodiesel production from microalgal lipids and for CO2 mitigation due to photoautotrophic growth of microalgae have recently been recognized. Microalgae biomass also has other valuable components, including carbohydrates, long chain fatty acids, pigments and proteins. The microalgae-based carbohydrates consist mainly of cellulose and starch without lignin; thus they can be ready carbon source for the fermentation industry. Some microalgae can produce long chain fatty acids (such as DHA and EPA) as valuable health food supplements. In addition, microalgal pigments and proteins have considerable potential for many medical applications. This review article presents comprehensive information on the current state of these commercial applications, as well as the utilization and characteristics of the microalgal components, in addition to the key factors and challenges that should be addressed during the production of these materials, and thus provides a useful report that can aid the development of an efficient microalgae-based biorefinery process.
微藻油脂具有生产生物柴油的潜力，并且微藻的光合作用可以减少二氧化碳，这一点最近得到了认可。微藻生物质还具有其他有价值的成分，包括碳水化合物、长链脂肪酸、色素和蛋白质。基于微藻的碳水化合物主要由纤维素和淀粉组成，不含木质素；因此，它们可以作为发酵工业的现成碳源。一些微藻可以产生长链脂肪酸（如 DHA 和 EPA），作为有价值的保健品。此外，微藻色素和蛋白质在许多医学应用中具有相当大的潜力。本文综述了这些商业应用的最新现状，以及微藻成分的利用和特性，此外还介绍了在这些材料生产过程中应解决的关键因素和挑战，因此提供了一份有用的报告，可帮助开发高效的基于微藻的生物炼制工艺。
