世界各国木质纤维原料生物转化燃料乙醇的工业化进程

Industrialization Course of Bioconversion of Fuel Alcohol by Cellulosic Materials around the World

充分利用数量巨大的可再生资源将纤维素生物质转化为燃料酒精。各国对纤维质原料生产燃料酒精的研究主要集中在原材料的预处理、如何降低纤维素酶的成本、发酵过程的优化、菌种的合理运用和改造、酒精废糟的综合利用等方面。主要介绍美国、加拿大、日本、瑞典、中国等国家在利用纤维质生产乙醇方面的研发以及未来产业化的发展趋势。

The plentiful renewable resources-cellulosic materials could be used to produce fuel alcohol through bioconversion. The research on bioconversion of cellulosic materials to produce fuel alcohol around the world mainly focused on the pretreatment of raw materials, the approaches to reduce cellulase cost, the optimization of fermentation course, appropriate use and transformation of microbial species, and the comprehensive use of waste distiller＇s materials etc. In thispaper, the present status of fuel alcohol production by cellulosic materials and the industrilization trend in the near future in the United States, Japan, Canada, Sweden and China were introduced.
