摘　　要：木质纤维素类生物质作为一种廉价且储量丰富的可再生原料,可通过预处理、酶解和微生物发酵等过程转化为纤维素燃料乙醇,近几十年来受到世界各国的广泛关注。杨木是一种人工广泛种植的速生硬木,主要用于造纸工业,而伴随产生大量枝桠等废弃物。因其富含纤维素和半纤维素组分,被认为是纤维素乙醇生产的优良木质纤维素原料。聚焦于杨木在纤维素乙醇生产中的应用,介绍了杨木的组成及结构特点,重点综述了杨木在预处理技术、预处理原料的酶解、微生物发酵等方面的研究进展。最后,归纳总结了限制杨木在纤维素乙醇应用中的技术障碍及困难,进而分析提出了相应解决对策并展望了其应用前景。As a cheap and abundant renewable raw material,lignocellulosic biomass can be converted into cellulosic fuel ethanol through pretreatment,enzymatic hydrolysis and microbial fermentation,etc.,which has widely attracted attention in recent decades.Poplar is a kind of fast-growing hardwood that is widely artificially cultivated and is mainly used in papermaking industry.Poplar is considered as an excellent lignocellulosic material for the production of cellulosic ethanol due to its high contents in cellulose and hemicellulose components.The application of poplar in cellulosic ethanol production was focused on in this paper,including briefly introducing the composition and structural characteristics of poplar,and importantly overviewing the research progress of poplar in pretreatment technology,enzymatic hydrolysis of pretreatment raw materials and microbial fermentation and so on.Finally,the technical obstacles and difficulties restricting the application of poplar in cellulosic ethanol industry were summarized,and the corresponding countermeasures were analyzed and the application were prospected.
