Abstract: The disclosure provides a process for the production of ethanol and one or more low boiling compound from a fermentable carbon source. The ethanol and the low boiling compound(s) are produced using an ethanol-producing yeast modified to further produce the one or more low boiling point compounds. In one embodiment, the low boiling compound(s) are acetone, 1-propanol, and/or 2-propanol. Additionally, the disclosure provides a process for the isolation ad purification of the one or more low boiling compounds from ethanol.
