1. A method of increasing the production of a fermentation product during a fermentation, said method comprising contacting a medium with (i) a recombinant yeast host cell comprising a first genetic modification for expressing a heterologous glucose-inactivated glycerol proton symporter STL1 (STL1) protein and (ii) a trehalase, wherein the production of the fermentation product is increased when compared to a control method with a control yeast host cell lacking the first genetic modification.
