METHODS OF PROCESSING EMPTY FRUIT BUNCHES (EFB) TO FERMENTABLE SUGARS USING MULTIPLE-STAGE ENZYMATIC HYDROLYSIS

摘要

Provided are methods of processing empty fruit bunches (EFB) using cellulase enzymatic hydrolysis in multiple stages. Hydrolysis yields are improved in a multiple-stage process featuring at least one solid/liquid separation step to an extent that is surprisingly great, much more than can be accounted for by alleviation of glucose product inhibition of cellulase enzymes.
