| Abstract: | Based on the analysis of the principle of fuel ethanol production from lignocellulose biomass,the fermentation process of fuel ethanol production is mainly discussed.At present,the fermentation process mainly includes direct fermentation,separate enzymatic hydrolysis and fermentation,simultaneous saccharification and fermentation,simultaneous saccharification and co-fermentation,and consolidated bioprocessing.The research status of these technologies is analyzed and their development trends are prospected.Consolidated bioprocessing conducted by highly efficient fermentation strains constructed by genetic engineering will be the development trend of high-efficiency fermentation technology in the future.The aim of this paper is to provide an important reference for effectively improving the substrate metabolic ability of fermentation strains and obtaining high ethanol yield. |
