Separation and extraction method for lignin hydrolyzed by enzyme

酶解木质素的分离提取方法

Abstract

本发明公开了两种酶解木质素的分离提取方法。利用微生物酶解玉米秸杆中的糖分制备能源酒精是克服石油短缺所造成的能源危机的有效途径之一。本发明分别采用有机溶剂萃取和无机化学品处理的方法从微生物酶解玉米秸杆的残渣中分离提取获得酶解木质素。在制备能源酒精的微生物发酵和从残渣分离的过程中酶解木质素都处在相对温和的状态下,因此酶解木质素较好地保留了木质素的活性基团,适于制备木质素的改性产品,有良好的经济价值。从微生物酶解玉米秸杆的残渣中分离提取酶解木质素可以解决微生物酶解玉米秸杆制备能源酒精工艺的亏损问题,将有利于推广这种绿色环保的新工艺,有利于可持续发展。
The present invention discloses two enzymolyzed lignin separating and extracting methods. Enzymolyzing saccharides in corn stalk with microbe to prepare alcohol is one effective way of solving energy crisis problem, and the present invention separates and extracts enzymolyzed lignin from microbe enzymolyzed corn stalk residue by means of organic solvent extraction and inorganic chemical treatment. During microbe fermentation and residue separation for preparing alcohol, enzymolyzed lignin is always in relatively mild state, so that the enzymolyzed lignin has the active groups of lignin well maintained. The present invention is suitable for modified lignin product in high economic value.
