PCT No. PCT/FI90/00206 Sec. 371 Date Mar. 27, 1992 Sec. 102(e) Date Mar. 27, 1992 PCT Filed Sep. 21, 1990 PCT Pub. No. WO91/03566 PCT Pub. Date Mar. 21, 1991The invention relates to a process for the hydrolysis of a hemicellulose substrate containing xylo-oligomers with an immobilized enzyme by adjusting the pH of an aqueous solution containing hemicellulose oligosaccharides and optionally ionic components to a value within a weakly acidic range, and contacting the solution with a hemicellulolytic enzyme or mixture of enzymes immobilized on a regenerable weak cation exchange carrier without fixing additives, and recovering xylose from the solution. The invention also concerns an enzyme preparation to be used in the process, comprising a weak cation exchange carrier and a hemicellulolytic enzyme or mixture of enzymes immobilized on said carrier. |
