助剂强化碱预处理对玉米秸秆酶解糖化的影响
Effects of alkaline pretreatment enhanced by additives on the enzymatic saccharification of corn straw
摘要
Abstract
The effects of alkaline pretreatment enhanced by additives on the enzymatic sac-charification of corn straw were analyzed based on previous study.Results show that the solid content in the extract is higher for higher additive dosage,while the variation trend of xylose yield is increased for the alkaline pretreatment enhanced by two additives,H2 O2 or Tween-80.The sugars yield (based on the total carbohydrates in raw materials)of pretreated sub-strate shows different degree of rise after enzymatic hydrolysis.Under certain conditions,the total reducing sugar yield and weight loss are higher for higher additive dosage or alkali con-centration.Finally considering all factors,including the additive dosage,the cost,the efficien-cy of enzyme hydrolysis and so on,the pretreatment of NaOH+Tween-80 exhibits a relative-ly better effect.关键词
