Description
Summary:	The production of ethanol by S. rosei UWO(PS) 80-38 been studied using pure non-hydrolyzed inulin and purified Jerusalem artichoke extracts as the substrates and the effects of aeration and yeast extract examined. With Jerusalem artichoke extract as the fermentation medium, ethanol yields of up to 70% of the theoretical were achieved whereas yields were low (30%) when pure non-hydrolyzed inulin was used as the substrate. The addition of yeast extract stimulated the rate of ethanol production. It was concluded that the degree of hydrolysis of inulin plays a decisive role on the rates and yields of ethanol production.
