Overview of fermentation results. Growth rate (a), fermentation product yields on glucose (b), and carbon balance per mole of glucose (c) of the series of batch fermentations presented in Fig. 3. Error bars represent standard deviaitons. The carbon balance is calculated by converting glucose to C-moles (i.e. multiplied by 6) and multiplying succinate, acetate, lactate, and ethanol by 3
