Abstract
New yeast strains providing for an enhanced rate of the fermentation of sugars, and a process to obtain such yeasts and the use of these yeasts. Yeasts capable of improved fermentation of sugars, a process to obtain these yeasts and the use of these yeasts are provided. The yeasts show higher rates of metabolism resulting in for example higher carbon dioxide and ethanol production in media containing sugars, such as maltose, as main carbon and energy source. The fermentation rate of sugars is improved by the introduction into a yeast of one or more DNA constructs comprising at least one gene encoding a protein promoting the uptake and/or initial metabolic conversion of a transported sugar substrate.
