A PROCESS FOR HYDROLYZING HEMICELLULOSE BY ENZYMES PRODUCED BY TRICHODERMA REESEI

摘要

The invention concerns a process for hydrolyzing hemicelluloses, especially xylan, using an enzyme preparation isolated from Trichoderma reesei, containing an endo- beta -xylanase I (pI 5.5) and an endo- beta -xylanase II (pI 9.0). The invention further concerns the use of this enzyme preparation in the improving of the sheet properties and the bleachability of pulps and for the production of sugars from hemicellulosic substrates.
