摘要
在分析木质纤维素类生物质制备燃料乙醇原理基础上,重点对燃料乙醇转化过程的发酵工艺进行了论述。目前乙醇发酵工艺主要包括直接发酵、分步糖化发酵、同步糖化发酵、同步糖化共发酵和联合生物加工技术等,对这几种技术的研究现状进行了分析并对其发展趋势进行了展望,通过基因工程构建高效发酵菌种的联合生物加工技术将是未来高效发酵工艺的发展趋势,旨在为有效提高发酵菌株的底物代谢能力,获得高的乙醇产量提供重要参考。
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.
