Abstract
The anaerobic metabolism of Enterobacter aerogenes was studied in batch culture at increasing initial glucose levels (9.0< S(o) <72 g l(-1)). The ultimate concentrations of fermentation products were utilized to check a metabolic flux analysis based on simple carbon mass and energy balances that promise to be suitable for the study of different fermentation processes, either under aerobic or anaerobic conditions. The stoichiometric coefficients of products collected at increasing starting glucose concentrations under anaerobic conditions suggest: (a) little influence of starting glucose level on the formation of the main fermentation products (2,3-butanediol and ethanol); (b) possible inhibition of 2,3-butanediol and lactate formations by increased ethanol concentration; (c) consequent increase in carbon flux through the remaining metabolic pathways with increased molar productions of succinate, acetate and hydrogen; (d) relative constancy of the molar production of ATP and CO(2).
