Beschreibung
Zusammenfassung:	The invention relates to a process for the production of ethanol, the process comprising fermenting of a carbon source composition with a recombinant yeast,wherein the carbon source composition comprises at least glucose and arabinose; andwherein the recombinant yeast comprises arabinose isomerase activity, ribulokinase activity, ribulose phosphate epimerase activity, glycerol uptake activity and glycerol conversion capacity; andwherein the recombinant yeast further comprises a genetic modification leading to the reduction, downregulation, inhibition and/or elimination of the activity of a homologous protein with glycerol-efflux activity; andwherein each of the glucose and the arabinose is converted into ethanol.In addition, the invention relates to a recombinant yeast that can be used in such a process.
