초록
본 연구에서는 바이오 에탄올 생산을 위한 보릿짚의 전처리에 ethanosolv 방법을 적용하여 그 타당성을 조사하였다. 리그닌제거율은 처리 온도와 시간에 따라 증가 하였으며
Lignocellulose represents a key sustainable source of biomass for transformation into biofuels and bio-based products. Unfortunately, lignocellulosic biomass is highly recalcitrant to biotransformation, both microbial and enzymatic, which limits its use and prevents. As a result, effective pretreatment strategies are necessary. The vast majority of pretreatment strategies have focused on achieving a reduction of lignin content. In this work, an ethanosolv pretreatment has been evaluated for extracting lignin from barley straw. 75% ethanol was used as a pretreatment solvent to extract lignin from barley straw. The influence on delignification of three independent variables are temperature, time, catalyst (1 M
