## Cell retention and ethanol production using the flocculent bacterium Zymomonas mobilis NPRL B-12526 were studied in three bioreactor configurations. The flocculent growth characteristic of this strain and a special reactor design were combined to achieve relatively high cell concentrations in

## Previous studies have demonstrated that Zymomonas mobilis is a very promising organism for ethanol production. In the present study comparative kinetic data from batch and continuous cultures on glucose media are presented which show that a new strain of Z. mobilis has higher specific rates o
A flocculent mutant of Z~momonas mobilis has been isolated and kinetic studies carried out in batch and continuous culture. By comparison with the parent strain the specific rates of glucose uptake and ethanol production were decreased by 20%. Cell recycle and semibatch cultures with the floccule
