Recent work from the authors laboratory has shown that, compared to yeasts, much higher ethanol productivity and yield can be obtained in batch or continuous cultures using the bacterium Zymomonas mobilis grown on fructose media. In batch culture, hydrolyzed Jerusalem artichoke juice with sugar concentrations ranging from 100 to 250 g/L can be converted efficiently to ethanol. The present work describes the conversion of the hydrolyzed juice to ethanol in continuous culture. The extraction and enzymatic hydrolysis of inulin from the tubers of Jerusalem artichoke is also reported.
