甘蔗渣活性氧脱木素及其对纤维素酶解的影响
Effects of Reactive Oxygen on Bagasse Delignification and the Cellulase Hydrolysis
摘要
Abstract
This study established a novel process by using reactive oxygen (H2O2 and O2) delignification of bagasse to explore the effect of lignin content of bagasse .In a typical experiment, the treatment conditions were as follow: temperature of 145℃-165℃, oxygen pressure of 0 Mpa~1.2 Mpa,the amount of Mg-based Oxides of 0~10.0g and concentration of H2O2 of 0-16%. Then the bagasse was used as raw materials for cellulase hydrolysis to investigate the sugar yield of enzymatic hydrolysis. The result showed that the reactive oxygen delignification could effectively enhance the sugar yield of enzymatic hydrolysis of bagasse and delignification rate. The rate of lignin removal was up to 96.23% and the sugar yield of the enzymatic hydrolysis was 52.36%. After delignification with reactive oxygen, a great deal of lignin in bagasse were removed, which was in favor of the enzymatic hydrolysis.关键词
