P-13 Effects of the combined pretreatments with milling on enzymatic saccharification of cellulosic biomass

Abstract

In this study, we focused on the use of mechanochemical grinding for woody biomass pretreatment. In attempts to improve the efficiency of wood-based bioethanol production, we used Japanese-cedar coarse sawdust as the raw material to investigate converge mill grinding in combination with various other pre-processing techniques, by quantitatively determining the relationship between the pretreatment method and enzymatic saccharification. We achieved a saccharification ratio of 80% or more after pre-processing by hammer mill grinding for approximately 1 mm followed by converge mill grinding for as little as 20 mm.
