Summary
Saccharomyces cerevisiae cells were immobilized on cotton cloth. The resulting yeast films were placed in parallel in a rectangular fermentor which was designed for scale-up. Ethanol production from sugars in the hydrolysate of Jerusalem artichoke tubers was studied in three modes of operation: batch, circulated batch and continuous flow. Circulated batch fermentation gave the shortest time of fermentation and accordingly the highest average ethanol productivity.
