Butanol is acknowledged as a drop-in biofuel that can be used in the existing transportation infrastructure, addressing the needs for sustainable liquid fuel. However, before becoming a thoughtful alternative for fossil fuel, butanol should be produced efficiently from a widely-available, renewable, and cost-effective source. In this regard, lignocellulosic materials, the main component of organic wastes from agriculture, forestry, municipalities, and even industries seems to be the most promising source. The butanol-producing bacteria, i.e., Clostridia sp., can uptake a wide range of hexoses, pentoses, and oligomers obtained from hydrolysis of cellulose and hemicellulose content of lignocelluloses. The present work is dedicated to reviewing different processes containing pretreatment and hydrolysis of hemicellulose and cellulose developed for preparing fermentable hydrolysates for biobutanol production.
丁醇被认为是一种可替代的生物燃料，可以在现有的交通基础设施中使用，满足对可持续液体燃料的需求。然而，在成为化石燃料的一种可行替代品之前，丁醇应该能够从广泛可用、可再生且具有成本效益的来源中高效生产。在这方面，木质纤维素材料，即农业、林业、市政甚至工业的有机废物的主要成分，似乎是最有前途的来源。生产丁醇的细菌，即梭菌属，可以摄取从纤维素水解和木质纤维素的半纤维素含量中获得的各种己糖、戊糖和低聚物。本工作致力于综述不同的预处理和半纤维素及纤维素水解工艺，用于制备可发酵的水解物以生产生物丁醇。
