Abstract

Replacement of conventional transportation fuels with biofuels will require production of compounds that can cover the complete fuel spectrum, ranging from gasoline to kerosene. Advanced biofuels are expected to play an important role in replacing fossil fuels because they have improved properties compared with ethanol and some of these may have the energy density required for use in heavy duty vehicles, ships, and aviation. Moreover, advanced biofuels can be used as drop-in fuels in existing internal combustion engines. The yeast cell factory Saccharomyces cerevisiae can be turned into a producer of higher alcohols (1-butanol and isobutanol), sesquiterpenes (farnesene and bisabolene), and fatty acid ethyl esters (biodiesel), and here we discusses progress in metabolic engineering of S. cerevisiae for production of these advanced biofuels.

摘要

用生物燃料替代传统交通燃料将需要生产能够涵盖完整燃料谱的化合物,范围从汽油到煤油。先进的生物燃料有望在替代化石燃料方面发挥重要作用,因为与乙醇相比,它们具有更好的性能,而且其中一些可能具有用于重型车辆、船舶和航空的所需能量密度。此外,先进的生物燃料可作为现有内燃机的即用型燃料。酵母细胞工厂酿酒酵母可以被转化为生产高级醇(1-丁醇和异丁醇)、倍半萜(法呢烯和双环烯)和脂肪酸乙酯(生物柴油)的生产者,在这里我们讨论了酿酒酵母生产这些先进生物燃料的代谢工程方面的进展。
