木质纤维材料的工业加工只利用了纤维素组分的己糖成分。在大多数情况下，半纤维素组分中存在的戊糖和一些较小的己糖，可能占木质纤维生物量的40%，已经被浪费。半纤维素糖缺乏良好的利用方法是阻碍木质纤维素乙醇和其他生物燃料发展的一个关键障碍。在这一章中，我们重点介绍了半纤维素的利用、半纤维素的结构及其水解，以及将其转化为有价值的燃料和化学品所涉及的生化和加工技术。
Industrial processes of lignocellulosic material have made use of only the hexose component of the cellulose fraction. Pentoses and some minor hexoses present in the hemicellulose fraction, which may represent as much as 40% of lignocellulosic biomass, have in most cases been wasted. The lack of good methods for utilization of hemicellulose sugars is a key obstacle hindering the development of lignocellulose-based ethanol and other biofuels. In this chapter, we focus on the utilization of hemicellulose sugars, the structure of hemicellulose and its hydrolysis, and the biochemistry and process technology involved in their conversion to valuable fuels and chemicals.
