Abstract
An ion-exchange sponge that can have a tailored surface charge has bee n used for yeast immobilisation in high original gravity (o.g. 1.106) cider fermentation. Continuous circulation of fermentation medium thro ugh columns containing weakly basic sponge encouraged yeast growth, de creased batch fermentation time and increased final ethanol concentrat ion, possibly aided by sponge enhanced CO2 removal from solution.
