Lmt.The characteristics and novelty in this dissertation was obvious in the following aspects: cofermentation of glucose and xylose to ethanol by recombinant yeast S. cerevisiae ZU-10, ethanol production from hydrolysates of cellulose and hemicellulose in corn stover by recombinant yeast S. cerevisiae ZU-10, and integration of key technologies in ethanol production from lignocellulosic biomass. These results were meaningful not only in academic research, also in utilization of renewable lignocellulosic biomass, decreasing the production cost of fuel ethanol , and alleviating the world grain crisis.
