We studied the effect of the initial substrate concentration over the range of 100-250 g・l^<-1> on the fermentation kinetics in batch cultures of Zymomonas mobilis NRRL B-4286 on glucose, fructose, and sucrose, using an adapted initial inoculum. With increasing concentrations of substrate, parameters related to growth were more rapidly and strongly affected than those related to ethanol production. This strain produced 94.0 g・l^<-1>, 76.9 g・l^<-1>, and 66.5 g・l^<-1> of ethanol at glucose, fructose, and sucrose concentrations of 200 g・l^<-1>, respectively, more than the amont produced by the efficient stiain ZM4 (NRRL B-14023).
