玉米秸秆中不同木质素脱除方法对纤维素酶吸附及酶解效果的比较OA北大核心CSCDCSTPCD
Comparison of different lignin removal processes for corn stover on cellulase adsorption and enzymatic hydrolysis
利用不同预处理方法获得的玉米秸秆底物研究木质素脱除对纤维素酶吸附量及酶解效率的影响.相比于其他处理方法,2%(质量分数)NaOH处理的底物具有最高的木质素脱除率(85%),最高的底物可及性[4.7 mg·(g葡聚糖)?1]及酶解效率(18.9%).通过对不同处理获得的底物进行Langmuir吸附等温曲线模拟,获得了最大吸附量(Wmax)与吸附平衡常数(K),且木质纤维素酶水解效率与纤维素酶吸附量具有很好的线性关系(R2>0.8),表明脱除木…查看全部>>
Experiments were conducted for various pretreated substrates to investigate the impact of lignin content on cellulase adsorption and substrate digestibility. Compared with other treatments, 2% (mass) NaOH pretreated solids with the highest level of lignin removal (85%) exhibited the highest accessibility to cellulase [4.7 mg protein·(gglucan)?1] and enzymatic digestibility (18.9%). The obtained maximum adsorption capacity (Wmax) and equilibrium constan…查看全部>>
