Patent ID: 8709763

Claim:
A process of production of fermentable sugars from a mixture of hemicellulose and cellulose using a multi-step multi-enzyme system, the process comprising: a. treating said mixture of hemicellulose and cellulose with endo-glucanases, exo-glucanases, endo-xylanases, exo-xylanases, mannanases and galactanases at a temperature ranging from 30° C. to 90° C. to obtain a hydrolysate; b. separating the hydrolysate from the at least one enzyme used in step (a) to obtain a solution comprising oligosaccharides, disaccharides, and monosugars; and c. treating the solution with xylosidases, mannosidases and glucosidases to obtain the fermentable sugars.
