| Abstract: | The present situation of research on utilization of xylanases in pulp biobleaching was reviewed in detail.The changes of the structure of hemicelluloses in pulping processes,the effect of using xylanase and other chemical reagents such as oxygen,hydrogen peroxide and ozone,etc.on the bleaching result,the effects of cellulases contained in xylanases on bleaching performance of the pulp,the effects of endo-xylanase and xylosidase in xylanase system,endoglucanase,extroglucannase and cellobiase in cellulase system on bleaching properties of the pulp were systematically reviewed,and the composition of xylanases particularly suitable for pulp biobleaching was suggested.The mechanism of enzyme-aided bleaching was summarized. |
