Abstract
The present invention relates to genetically engineered yeasts having a heterologous trehalase gene and fermentation processes for using such yeasts. The yeasts can express trehalase in a quantity sufficient to convert significant amounts of trehalose to glucose, thereby improving the yield of the product in a fermentation, and/or reducing or eliminating the need to add exogenous trehalase to the fermentation. The yeasts can also include other heterologous genes for expressing enzymes useful for improving yield and/or for reducing or eliminating the need to add exogenous enzymes to the fermentation.
