Summary

A flocculent mutant of Zymomonas 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 flocculent strain resulted in relatively high productivities (viz. 50 g/l/h). However semibatch culture had the additional advantages of an increased ethanol concentration (viz. 82 g/l) and a more stable and controlled environment for cell separation.
