| 摘要 |
Embodiments of the present invention include methods for the production of four carbon alcohols, specifically n-butanol, by a consolidated bioprocessing approach for the conversion of cellulosic material to the desired end product. According to some embodiments, recombinant microbial host cells are provided, preferably S. cerevisiae, that are capable of converting cellulosic material to butanol and include butanol biosynthetic pathway genes and cellulase genes. According to some embodiments, recombinant microbial host cells are provided, preferably S. cerevisiae, that are capable of converting hemicellulosic material to butanol and include cellulase genes, butanol biosynthetic pathway genes and at least one gene for the conversion of a pentose sugar. |
