Fig. 2
a Time-course of cellular growth and galactose consumption profiles of the parental (JHL59, open symbol) and engineered (GAL_059, closed symbol) strains in galactose supplemented minimal M9 medium for 14 h. The left y-axis represents OD600 in log scale and the right y-axis represents galactose concentration (g/L). The x-axis represents time in culture (h). Both the maximum specific growth rate (b) and the maximum specific sugar uptake rate (c) were higher in case of the engineered strain (GAL_059). The error bars indicate standard deviations of measurements from two independent cultures. Symbols: circle OD600; rectangle galactose
