Title (EN) ETHANOL FERMENTATION METHOD WITH SURFACTANT IMPROVEMENT
(FR) PROCÉDÉ DE FERMENTATION D'ÉTHANOL À AMÉLIORATION DU TENSIOACTIF
(ZH) 一种表面活性剂改进的乙醇发酵法
Abstract: front page image
(EN)An ethanol fermentation method with surfactant improvement comprises: adding a nonionic surfactant in a fermentation medium, yeast cells and the surfactant being capable of being recycled. The method improves the survival rate of yeast cells and the concentration of final ethanol in the fermentation of very high gravity ethanol, and reduces the production cost.
(FR)L'invention concerne un procédé de fermentation d'éthanol à amélioration du tensioactif, qui comprend les étapes suivantes : ajouter un tensioactif non ionique dans un milieu de fermentation, des cellules de levure et le tensioactif étant capables d'être recyclés. Ledit procédé améliore le taux de survie de cellules de levure et la concentration de l'éthanol final dans la fermentation de l'éthanol de très haute densité, et réduit les coûts de production.
(ZH)一种表面活性剂改进的乙醇发酵法,包括在发酵培养基中添加非离子表面活性剂,酵母细胞和表面活性剂可以回收再利用。该方法提高了超高浓度乙醇发酵液中酵母细胞的存活率和终点乙醇浓度,降低了生产成本。
