Riview on the Development of the Pentose Ethanol Fermentation

Ethanol fermentation from pentose is the key technology which uses the plant fibre resources economically and workably manufacture ethanol,and this paper presents a review of the research and development for ethanol fermentation from pentose.There are many microorganisms used for ethanol fermentation from pentose which mainly adopt yeasts to produce ethanol at present.In the yeast,there are two main approach of fermentation: xylulose route and xylose route.Nowadays,the yeast stem selection mostly contains four aspects and the fermentation modes contain five types.
