The Figure 4.20 shows the profile growth of Escherichia coli type K-12 which was cultured in 20 g/L of glycerol treated with supplements from a carbon source under anaerobic condition and the medium supplemented with 10 g/L of trypton. About 10% working volume of inoculums were added to the medium for the profile growth process. The effects on growth curves of strains of Escherichia coli were investigated by measuring the concentration of succinic acid produced and its optical density by using HPLC
