PROCESS FOR THE ENZYMATIC CONVERSION OF LIGNOCELLULOSIC BIOMASS

摘要

The present invention provides a process for the enzymatic conversion of pretreated lignocellulosic biomass to fermentable sugars and fermentation products, the process including the steps of saccharification of at least a portion of the cellulose and/or hemicellulose in the pretreated biomass with an enzyme mixture comprising cellulase and/or hemicellulase enzymes, to obtain a partially-hydrolyzed biomass, followed by mechanical treatment of the partially-hydrolyzed biomass, and further saccharification of the mechanically-treated, partially hydrolyzed biomass with or without further addition of an enzyme mixture.
