Abstract
The invention is directed to a liquefied sugar beet and/or sugar cane biomass material as well as production methods and uses thereof. The liquefied biomass is storage stable and can be used for the production of a product resulting from fermentation.
Claims14
Process for the production of a liquefied product, comprising the following steps:
- (a) providing sugar beet and/or sugar cane biomass material;
- (b) liquefying said biomass by subjecting it to the enzymatic action of an enzyme mixture comprising cellobiohydrolase, beta-glucosidase, and polygalacturonase to a liquefied product;
- wherein the enzyme mixture additionally contains arabinose,
- wherein step (b) is carried out for less than 10 hours and
- wherein the liquefied product in step (b) has a content of remaining insoluble solids of less than 2% (w/w).
