自然界最重要的生物过程之一是木质纤维素材料降解为二氧化碳、水和腐殖质。这意味着在纸浆和造纸工业中使用生物技术的可能性，因此，使用微生物及其酶来替代或补充化学方法正在引起人们的兴趣。本章介绍木材的结构和主要木材成分：纤维素、半纤维素和木质素。详细描述了真菌和细菌用来修饰和降解这些成分的酶和酶机制。还描述了如何测定这些酶活性的技术。讨论了基于这些酶的生物技术在纸浆和造纸工业以及其他纤维利用工业中的可能性。
One of natures most important biological processes is the degradation of lignocellulosic materials to carbon dioxide, water and humic substances. This implies possibilities to use biotechnology in the pulp and paper industry and consequently, the use of microorganisms and their enzymes to replace or supplement chemical methods is gaining interest. This chapter describes the structure of wood and the main wood components, cellulose, hemicelluloses and lignins. The enzyme and enzyme mechanisms used by fungi and bacteria to modify and degrade these components are described in detail. Techniques for how to assay for these enzyme activities are also described. The possibilities for biotechnology in the pulp and paper industry and other fiber utilizing industries based on these enzymes are discussed.
