| | This paper studied birch powder pretreated by combining ultra-low temperature freezing whith superfine grinding treatment together.The pretreated lignocellulose powder was hydrolyzed by cellulase to yield the highest level of cellulose hydrolysis sugar.The optimal saccharification conditions were:temperature 45℃,pH value 4.8 and enzyme dosage 20IU/g substrate.The saccharification yield was 31.78 percent which increased by 28.68% over the raw birch powder.Reducing sugar yield is 243.67mg/g substrate. | | 采用超低温冷冻结合超微粉碎的方法对白桦木质纤维素进行预处理,并用纤维素酶对由预处理获得的超微粉体进行酶解,以提高其糖转化率,得到白桦木质纤维素最佳糖化条件:温度45℃,pH值4.8,酶用量20IU/g,糖化率为31.78%,还原糖产量为243.67 mg/g(底物)。较未经过预处理的白桦木质纤维素糖转化率提高了28.68%。 | | 文摘来源 | |   |
