Abstract

This invention relates to a method for increasing the speed and extent of fermentations. According to the method in the fermentation is used a yeast strain transformed with a DNA molecule comprising a nucleotide sequence that encodes part of the amino acid sequence for an a-glucoside transporter. The transformation converts the transformed host to have increased capacity for transport of maltose or maltotriose, or both compared to an untransformed host. The invention relates also to a method for preparing a yeast strain for fermentation, a new yeast strain and a DNA integration cassette.
