Abstract
The present invention relates to a genetically engineered yeast (e.g., Crabtree negative) that express a heterologous xylose isomerase. In a fermentation method the engineered yeast are capable of producing a bioproduct, such as ethanol, in a fermentation medium that includes xylose. Desirable bioproduct titers can be achieved when materials such as acetate are present in the fermentation medium.
