1.Introduction
Cellulases,hemicellulases and pectinases are industrially important enzymes that are sold in large volumes for use in different industrial applications.Among the application areas bio-polishing of textile,addition to washing powder,addition to animal feed to enhance its digestibility,pulping,processing of fruit juices and beverage,baking and in bioethanol production can be mentioned [1].
Substantial amounts of potential raw materials for different
kinds of bioprocesses can be found among lignocellulosic materials,such as agricultural,forestry and municipal waste.Sugar beet pulp is a waste product from sugar pulping,which is produced in volumes of 175,000 metric tonnes dry weight,yearly in Denmark (Bjarne Fallesen,Danisco Sugar,Naskov,personal communication).One of the major obstacles to use these raw materials in bioprocesses is its complex nature.Lignocellulosic materials are composed of the polymers cellulose,hemicellulose,pectin and lignin.For most applications,it is necessary to degrade the polymers to monomers,which can be done by physical,chemical or biological methods.Enzymatic hydrolysis of the lignocellulosic material has received attention due to its potential as an environmentally friendly process,which may provide an efficient and specific process technique [2–4].

1.言纤维素 半纤维素酶和果胶酶的重要工业酶所卖出大量使用在不同的工业应用.在应用领域的生物抛光,纺织,除了洗衣粉,除了动物性饲料,以提高其消化率 制浆,加工果汁和饮料,烤面包和原料生产可提到[1].大量潜在的原料不同bioprocesses可以发现其中lignocellulosic材料 如农业,林业和废物.甜菜浆是一种浪费,产品由糖业制浆,即生产量为175,000公吨,干重量 每年在丹麦(bjarnefallesen,鲢鱼糖,naskov,个人通讯).其中的主要障碍,利用这些原料bioprocesses有其复杂性.纤维素材料组成的聚合物纤维素,果胶和木质素.对于大多数应用,有必要降解的聚合物单体,可以做物理,化学或生物方法.酶解纤维素的材料也给予了高度重视,由于它的潜力,作为一个环保的过程中,它可提供一个高效率的和具体的工艺[2-4].
