Fuente: WIPO "stone fruits" Provided herein are genetically modified yeast cells that recombinantly express a gene encoding a fatty acid hydroxylase (FAH) enzyme, such as an oleate 12-hydroylase, and produce y-decalactone levels above an odor-threshold. Also provided herein are genetically modified yeast cells that recombinantly express genes encoding a fatty acid hydroxylase (FAH) enzyme, and one or more additional genes, such as an acyl-CoA desaturase 1 (OLE1) enzyme, a deregulated transcription factor, and/or an alcohol-O-acyltransferase (AAT) enzyme. Also provided are methods of producing fermented beverages and compositions comprising ethanol using the genetically modified yeast cells described herein.
