Ethanol Production by Xylose Fermenting Yeast Cultures Using a Mixture of Dextrose and Xylose
Abstract: Ever-increasing demand for motor fuels has led to the search for alternate sources of energy world over. Lignocellulosic biomass is the most abundant, renewable source which is being replenished through photosynthesis. In many developed countries, a number of “Biorefineries” have been set up to produce ethanol from plant biomass. However, ethanol productivities are still low. Moreover, distiller’s ethanologenic yeast Saccharomyces cerevisiae cannot utilize pentoses, with the result that about 30% …
