摘要：
An Aspergillus niger isolate produced about 2500 nkat xylanase/ml when cultivated in a medium containing 3% xylose. Application of the crude xylanolytic preparation to unbleached eucalyptus kraft pulp resulted in a decreased kappa number and increased brightness. Handsheets made from the xylanase-treated pulp after ECF bleaching retained good structural and mechanical characteristics.
