采用碱（Ca（OH）2）浸泡-电子束辐照（EBI）预处理油蒿（Artemisia ordosica），以提高其酶消化率。酶解72 h后，碱浸-EBI预处理的样品具有较高的还原糖得率。油蒿经碱浸-EBI预处理后，木质素和半纤维素含量降低。扫描电镜观察表明，碱浸-EBI预处理的油蒿表面受到严重侵蚀。对碱浸-EBI预处理和酶解工艺条件进行了优化。在此条件下，油蒿还原糖产量达到520.67 mg/g，比未处理对照提高了1136.75%。碱（Ca（OH）2）浸泡-EBI预处理油蒿是一种很有潜力的生物燃料生产方法。
Artemisia ordosica, a promising biofuel production material, was pretreated by alkali (Ca(OH)2) soaking-electron beam irradiation (EBI) to improve enzymatic digestibility. After 72 h enzymatic hydrolysis, alkali soaking-EBI pretreated sample showed high reducing sugar yield. The content of lignin and hemicellulose inArtemisia ordosicadecreased after alkali soaking-EBI pretreatment. SEM observation showed that theArtemisia ordosicasurface with alkali soaking-EBI pretreatment suffered serious erosion. The conditions of alkali soaking-EBI pretreatment and enzymatic hydrolysis were optimized. Under the optimal conditions, the reducing sugar yield ofArtemisia ordosicaachieved 520.67 mg/g, which increased by 1136.75% comparing to the untreated control group. TheArtemisia ordosicawith alkali (Ca(OH)2) soaking-EBI pretreatment is a promising potential for biofuel production.
