摘要：

Hemicellulases and an endoglucanase from seven different fungi were assessed for their potential to solubilze mannan and xylan from softwood sulfite dissolving pulps. A xylanase from Thermomyces lanuginosus and a mannanase from Sclerotium rolfsii acted synergistically on the pulp solubilizing 50% more mannan and 11% more xylan than did the individual enzymes. The addition of an endoglucanase further increased both the amount of xylan and mannan that was solubilized from the pulp.
