In this study, the COSLIF method for the pretreatment of lignocellulose biomass was employed to overcome the disadvantages of the conventional DA method. When lignocellulose biomass was hydrolyzed by the COSLIF method, dried rice straw produced glucose corresponding to 60.1%, while herbal medicine waste was found in 25.2%. The optimum conditions of the COSLIF method for the pretreatment of biomass were as follows: 84% phosphoric acid, 50oC, and 45 min. The COSLIF method for corn stover showed more lignin-removal characteristics than the DA method. Glucan digestibility in the COSLIF method at a high enzyme dosage was found to be 97% and at least 90% in 12 h and 24 h, respectively, while in the DA method, it was 84% in 72 h. In addition, at a low enzyme dosage, glucan digestibility was 93% in 24 h in the COSLIF method and 60% in 72 h in the DA method. This demonstrates that the COSLIF method is more efficient than the DA method.
