燃料乙醇生产研究进展

Progress of Fermentation Technology for Bioethanol Production

摘要: 燃料乙醇是发展最为成熟的生物质能源，能够解决能源短缺及环境污染等问题，在人类的新能源布局中占据重要地位。但燃料乙醇产业仍存在生产成本高、原料短缺等问题。本文对燃料乙醇发酵节能技术、途径工程改造生产菌种及非粮原料利用方面的研究进展进行了综述，分析了燃料乙醇发酵技术中存在的问题，并对今后进一步研究提出了建议。

Abstract: Bioethanol is the most mature biomass energy, which can solve energy shortage and pollution problems, oc-cupying the important position in the human new energy layout. But bioethanol industry had many problems such as high production costs and raw material shortages. In this paper, the new technologies including energy-saving fermenta-tion technology, pathway engineering to construct engineered strains and alternative materials were summarized. The developing direction for further investigation was discussed.
