Abstract

Spent wash from the Old Bushmill's Distillery Co. Ltd. was supplemented with either glucose (10% [w/v]) or cellulose (5% [w/v]) and used as a medium for the thermotolerant yeast strain Kluyveromyces marxianus IMB3. There was no significant difference in ethanol production during growth on these media at 45 degrees C, compared with that produced during growth on conventional, pre-defined laboratory media. On glucose supplemented spent wash ethanol yields were in the region of 45 g/L, representing 87% of the maximum theoretical yield. Analysis of spent media from the glucose-containing fermentations demonstrated that the total organic carbon (TOC) content was reduced by 36%. The results suggest a novel means of utilizing whiskey distiller spent wash.
