Summary
Using the Zymomonas mobilis NRRL B 14023 strain for ethanol fermentation with immobilized cells the combination of two external loop reactors followed by a plug flow reactor was the most effective reactor configuration. A maximal productivity of 92 and 108 g/l·h at practically complete sugar consumption was obtained with Carrageenan and Alginate catalysts respectively. Due to the high dilution rate nonsterile operation for extended periods of weeks was possible.
