A Bifunctional Xylanase-Glucanase with a Single Catalytic Domain from Paenibacillus sp.E18

【摘要】：正Hemicelluloses are the major constituents of plant cell walls.β-1,4-Xylans are mainly found in secondary cell walls of plants,and the mixed linked 1,3-1,4-β-glucans form the major part of cell walls of cereals like oat and barley~([1]).Xylanases in conjunction with other enzymes,such as cellulases,glucanases and proteases,are widely used in animal feed,brewing,food processing,waste treatment,as well as in
