• Starch from wheat flour was enzymatically hydrolyzed and used for ethanol production by Zymomonas mobilis. The addition of a nitrogen source like ammonium sulfate was sufficient to obtain a complete fermentation of the hydrolyzed starch. In batch culture a glucose concentration as high as 223 g/l could be fermented (conversion 99.5%) to 105 g/l of ethanol in 70 h with an ethanol yield of 0.47 g/g (92% of theoretical). In continuous culture the use of a flocculent strain and a fermentor with an internal settler resulted (at D=1,4 h^<-1>) in a high ethanol productivity of 70.7 g/l・h with : ethanol concentration 49.5 g/l, ethanol yield 0.50 g/g (98% of theoretical) and substrate conversion 99%.
