摘要
玉米秸秆是一种丰富的再生资源,主要由纤维素、半纤维素、木质素组成。经过预处理、水解、发酵可生产酒精。预处理方法主要有物理法、化学法、物理化学法及生物处理法;水解主要有酸水解法和酶水解法;发酵主要有直接发酵法、间接发酵法、同步糖化发酵法等。主要介绍玉米秸秆生产乙醇的关键技术进展情况。
The corn stalk mainly consisting of cellulose, hemicellulose and lignin is a wealth of renewable resources. After pretreatment, hy- drolysis and fermentation, the ethanol can be produced. The major pretreatment methods include physical, chemical, physicochemical and biological treatments. The acidic hydrolysis and enzymatic hydrolysis are the main methods of hydrolysis. Fermentation methods mainly include direct and indirect fermentation, as well as simultaneous saccharification and fermentation. This article mainly introduced the progress on the key technologies of ethanol production using Corn stalk.
