Abstract
Ethanol production using Zymomonas mobilis strains with medium optimized by response surface
methodology (RSM) was studied. A significant improvement in the ethanol yield (OSOg/g ethanol) was
demonstrated, resulting in very low residual sugar and fewer by-products. The five-factor and five-response full
factorial design have shown that glucose and yeast extract are the key media components that influence ethanol
production, followed by the inoculum concentration and ammonium sulfate, with phosphate showing little or
no effect. The composition (all in g/l) of the optimized medium was glucose 120.4, ammonium sulfate 0.96,
potassium dihydrogen phosphate 0.02, yeast extract 6.5, and magnesium sulfate 0.5. The optimum inoculum
concentration was log10 8.4 cells.
