摘要
蔗渣(髓)是丰富而廉价的可再生生物质资源,利用蔗渣(髓)代替传统的玉米等粮食作物为原料生产生物乙醇已成为研究热点。蔗渣(髓)转化为生物乙醇主要包括3个步骤:预处理脱去木质素、蔗渣(髓)中纤维素水解成还原糖、糖发酵成乙醇。本文阐述蔗渣(髓)经水解转化为生物乙醇处理技术的新进展,并展望其发展前景。
Sugarcane bagasse is an abundantly available,cheap and renewable resource,and its bioconversion to bio-ethanol has become the research hot spot.The bioconversion of sugarcane bagasse to bio-ethanol can be divided into three technological processes as follows:pretreatment for delignification,hydrolysis of cellulose in sugarcane bagasse to produce reducing sugars and fermentation of reducing sugars to produce bio-ethanol.New advances on the bioconversion technology of sugarcane bagasse to bio-ethanol were reviewed in this paper.And the prospect for application was discussed.
