Abstract
Genetically modified yeast having a heterologous sugar transporter that is capable of transporting a non-glucose sugar such as maltulose, are described. The heterologous sugar transporter can be a protein according to, or that has similarity to, SEQ ID NO: 44. Fermentation methods using enzymatically treated starch where the yeast are able to consume the non-glucose sugars, are also described. The engineered yeast can be useful for producing desired bioproducts such as high ethanol, with low amounts of residual sugars in the medium.
