CHANG Ken-Lin, CHEN Ximei, HAN Yeju, et al. Effect of surfactant-assisted ionic liquid pretreatment on enzymatic hydrolysis of rice straw[J]. CIESC Journal, 2016, (5): 2078-2083.
The enzymatic hydrolysis of lignocellulosic materials is a key stage for fuel ethanol production. Therefore
the pretreatment of lignocellulosic materials (as rice straw) is important to enhance the enzymatic hydrolysis saccharification. In this study
the rice straw was used as raw material and pretreatment by surfactant-assisted ionic liquid. Effects of pretreatment temperature and time
and adding proportion of surfactants on the enzymatic hydrolysis of rice straw were investigated. According to the result
the optimal condition for enzymatic hydrolysis of rice straw was at 110℃ for 60 min with 1% surfactants. To compare with the ionic liquid pretreatment of rice straw
cellulose conversion was increased by 8%—15%. The improvement of enzymatic hydrolysis was confirmed by rice straw composition analysis
