AB The culture media for glycerol to ethanol biotransformation by Escherichia coli underanaerobic conditions was optimized. A Plackett-Burman screening design was used todetermine which factors were significant with a 95% confidence interval. A full factorial 22and response surface model were employed to determine the optimum conditions for theselected response variable. The response variable considered in this work was biomassproductivity (QX). Profiles for biomass growth, glycerol consumption and ethanol productionwere obtained at optimum conditions and fermentation parameters were calculated.Glycerol to ethanol yield and ethanol specific productivity were determined to be 845 g kg 1of glycerol and 212 g kg 1 h 1 of cell mass respectively. Optimized culture media is presentedalong with the main results and experimental profiles obtained from this work.
