Influence of Alkali-laccase Degumming System on Controllable Delignification of Hemp Fibers

抄録

Four laccase degumming processing parameters including laccase concentration, time, liquor ratio and 2, 2'-Azinobis (3-ethylbenzothiazoline-6-sulfonic Acid Ammonium Salt) (ABTS) concentration were discussed in this paper. A controllable alkali-laccase degumming system and its regression equation for predicting the final lignin content were proposed. It was found that laccase as the enzyme, could remove the lignin efficiently with a mediator of ABTS after a pretreatment of the hot weak alkali solution. The whole process of alkali-laccase degumming system was mild, efficient and environment-friendly, indicating that it was feasible for the textile industry.
