Economic utilization of the hemicellulose fraction of lignocellulosics is required to enable the commercial exploitation of ethanol-from-lignocellulosics processes. By isomerizing xylose, the major hemicellulose sugar, to xylulose this substrate becomes fermentable by many yeasts. It is thought that conversion of xylose to ethanol is optimal in a packed-bed reactor system employing both immobilized glucose isomerase and immobilized Schizosaccharomyces pombe. Plug-flow models are employed in a preliminary discrimination between possible reactor schemes. A combined enzyme-yeast bed reactor is shown to be the most technically feasible and least costly alternative. 36 references, 8 figures, 5 tables.
