随着化石燃料储备的枯竭，迫切需要寻找可再生和具有成本效益的生物燃料生产战略。木质纤维生物质被认为是一种潜在的原料，有效的预处理和糖化是开发可行的生物燃料工艺的必要前提。最近在这方面采取的方法是：(1)研究极端微生物的酶，特别是嗜热菌，它们在这方面越来越重要，因为它们被发现在严酷的条件下是稳定的，催化效率更高；(2)由于离子液体的无毒性质，使用离子液体进行预处理正在成为一种更绿色的技术。开发/筛选耐离子液体的木质纤维素酶，以实现同时进行预处理和糖化，提供了一个有趣的选择；以及(3)设计/操作现有的木质纤维素酶，以获得理想的特性和可行的糖化和生物燃料产生过程。审查包括这些方法以及对该领域最新发展的关注。(C)2015爱思唯尔B.V.保留所有权利。
With the depletion of fossil fuel reserves, there is an urgent need to search for renewable and cost effective strategies for biofuel production. Lignocellulosic biomass has been perceived as a potential feedstock, wherein effective pretreatment and saccharification is necessary prerequisite for developing viable biofuel processes. Recent approaches in this context are, (i) studying enzymes from extremophilic organisms, particularly thermophiles which are gaining importance in this aspect as they are found to be stable and catalytically more effective under harsh conditions; (ii) usage of ionic liquids for pretreatment is emerging as a greener technology due to their non toxic nature. Developing/screening for ionic liquid tolerant lignocellulosic enzymes in order to attain simultaneous pretreatment and saccharification, offer an interesting option; and (iii) engineering/manipulating the existing lignocellulosic enzymes for desirable traits and viable saccharification and biofuel generation processes. The review encompasses these approaches and the focus on the recent development in the area. (C) 2015 Elsevier B.V. All rights reserved.
