MANUFACTURING METHOD FOR SUGAR SOLUTION AND DEVICE FOR SAME |
摘要 |
The present invention aims to provide a method for producing a sugar liquid by repeating a sugar liquid production process comprising the Steps (1) to (3) below:
(1) the step of adding a filamentous fungus-derived cellulase to cellulose to perform primary hydrolysis;
(2) the step of adding a fresh filamentous fungus-derived cellulase to the hydrolysate in Step (1) to perform secondary hydrolysis; and
(3) the step of subjecting the hydrolysate in Step (2) to solid-liquid separation to obtain a sugar liquid, from which a recovered enzyme is obtained;
wherein the recovered enzyme obtained in Step (3) is used for Step (1) of the next and later sugar liquid production processes. By this, the present invention provides a method for reducing the amount of enzyme used, such as cellulase, in a method for producing a sugar liquid from pretreated cellulose. |
