Much progress has been made since the discovery that some yeasts can ferment D-xylose to ethanol. We chose to investigate the aerobic mode of ethanol production by C. shehatae because high fermentation rates are obtained with low aeration using this organism. The objectives of this work were to determine the effects of important process variables such as aeration rate, D-xylose concentration and ethanol concentration on the fermentation rate, and to obtain high volumetric ethanol production rates. Continuous methods were used because they allow collection of accurate rate data at constant environmental conditions. We were especially interested in fermentation performance at high volumetric production rates.
