摘要：

褐藻作为第三代生物乙醇生产原料,以其高碳水化合物含量、生产周期短、不与粮争地的优势逐渐被人们所关注。但是在生物乙醇的实际生产中,低成本基础上乙醇产率的提高一直是亟需解决的问题。主要针对褐藻制备生物乙醇的技术困难,综述了适用于大规模生产生物乙醇的预处理技术和糖化发酵技术的研究进展,并由此展望褐藻制备生物乙醇的研究发展新方向。
关键词： 生物乙醇;  褐藻;  褐藻胶;  酿酒酵母    
Abstract:

As the third-generation bioethanol feedstocks, brown algae have received attention because of advantages with high carbohydrate content, short production cycle and haven’t compete with grain for land. However, the improvement of ethanol yield on the basis of low cost is an urgent problem in the actual production of bioethanol. The technical difficulties of large-scale bioethanol production from brown algae were focused on, the research progress of the pretreatment technology and the saccharification and fermentation technology were reviewed, and the prospects of the new potential trend of brown algae bioethanol were also provided.
Key words: Bioethanol    Brown algae    Alginate    Saccharomyces cerevisiae
