Title:
METHOD FOR IMPROVING ENZYMATIC SACCHARIFICATION YIELD OF LIGNOCELLULOSE
Document Type and Number:
WIPO Patent Application WO/2017/004951
Kind Code:
A1
Abstract:
Provided is a method for improving an enzymatic saccharification yield of lignocellulose. The method comprises: adding an anionic surfactant at a concentration as low as 0.5‰ and a cationic surfactant at a concentration of 0.01‰, thereby increasing a saccharification yield to 44-115%. The anionic surfactant is selected from ligin sulfonate and bisulfite of lignocellulose, both being pulp and paper byproducts.
