Lignocelluloses are rich sugar treasures, which can be converted to useful commodities such as biofuel with the help of efficient combination of enzymes and microbes. Although several bioprocessing approaches have been proposed, biofuel production from lignocelluloses is limited because of economically infeasible technologies for pretreatment, saccharification and fermentation. Use of consolidated bioprocessing (CBP) microbes is the most promising method for the cost-effective production of biofuels. However, lignocelluloses are obtained from highly diverse environment and hence are heterogeneous in nature. Therefore, it is necessary to develop and integrate tailor-designed pretreatment processes and efficient microbes that can thrive on many different kinds of biomass. In this review, the progress towards the construction of consolidated bioprocessing microbes, which can efficiently convert heterogeneous lignocellulosic biomass to bioenergy, has been discussed; in addition, the potential and constraints of current bioprocessing technologies for cellulosic biofuel production have been discussed.
木质纤维素是丰富的糖的宝库，可以在高效的酶和微生物的帮助下转化为有用的商品，如生物燃料。尽管已经提出了几种生物加工方法，但由于预处理、糖化和发酵的技术在经济上不可行，木质纤维素的生物燃料生产受到限制。使用整合生物加工（CBP）微生物是生产生物燃料具有成本效益的最有前途的方法。然而，木质纤维素来自高度多样化的环境，因此在性质上是异质的。因此，有必要开发和整合定制的预处理工艺和能够在许多不同种类的生物质上茁壮成长的高效微生物。在这篇综述中，讨论了构建能够高效转化异质木质纤维素生物质为生物能源的整合生物加工微生物的进展；此外，还讨论了当前纤维素生物燃料生产的生物加工技术的潜力和限制。
