| Popis: | Various ion exchange resins were tested for their ability to adsorb cells of Saccharomyces cerivisiae with the ultimate intention of developing a packed bed immobilized cell reactor for the continuous production of ethanol. The resins varied greatly in their ability to adsorb cells - the least effective resins retained less than 1 mg S. cerivisiae cells (dry weight)/g of resin (dry weight), and the most effective, 130–140 mg cells/g of resin. A column reactor packed with adsorbed yeast cells was operated continuously for over 200 hours using a 12% (w/v) glucose medium at dilution rates of 1.1 h-1 and 1.44 h-1 (based on void volume). High ethanol productivities of 53.1 and 62.0 g ethanol/l-h were obtained. |
