摘要： The present invention relates to isolated polypeptides having pectinase activity, and polynucleotides encoding the polypeptides. The invention also relates to nucleic acid constructs, vectors, and host cells comprising the polynucleotides as well as methods of producing and using the polypeptides.

摘要： The invention relates to processes of multi-stage hydrolysis where different enzyme compositions are added in at least two stages of hydrolysis. In a first stage, a first enzyme composition of xylanase, a beta-xylosidase and an endoglucanase is added, followed by a latter stage in which a second enzyme composition, a cellulolytic enzyme composition, is added. Also provided are processes for obtaining hydrolysis products and fermentation products using processes of the invention.

摘要： The invention relates to processes of closing an observed gap in sugar yield between pure batch hydrolysis and a multi-stage hydrolysis containing a continuous reactor. Enzyme compositions containing varied ratios of cellulolytic composition and a hemicellulolytic composition preconditioning are used in multi-stage hydrolysis processes containing a continuous reactor in order to close the gap. Such enzyme compositions are useful in multi-stage saccharification of a lignocellulosic material, fermentation processes following multi-stage saccharification of a lignocellulosic material and in improving a glucose or xylose yield in multi-stage saccharification of a lignocellulosic material.
