Genetically modified yeasts and fermentation processes using genetically modified yeasts

摘要

The present invention relates to a genetically engineered yeast capable of manufacturing a fermentation product using sucrose as a fermentation substrate, and fermentation processes using such a yeast. The yeast has an exogenous invertase gene and has a deletion or disruption of the PDC activity gene. Accordingly, the yeast is useful for manufacturing fermentation products other than ethanol from fermentation substrates containing sucrose.
