用于生产第一代乙醇的酵母菌株
Abstract:
本发明涉及相对于第一代乙醇生产中所用的专用菌株具有改进性质的酵母菌株。具体地，本发明的菌株具有增加的乙醇收率、较低的甘油产量和与标准菌株D1B相似或稍慢的乙醇生产动力学。本发明还涉及通过培养所述菌株获得的酵母，以及所述酵母和/或所述菌株用于工业生产乙醇的用途。
Abstract(English):

The present invention concerns yeast strains that have improved properties relative to the specialised strains that are used in the production of first-generation ethanol. In particular, the strains of the invention have an increased ethanol yield, a lower production of glycerol and ethanol production kinetics that are similar or slightly slower than standard strain D1B. The present invention also concerns the yeasts obtained by culturing said strains, and the use of said yeasts and/or of said strains in the industrial production of ethanol.
