Proton correlation nuclear magnetic resonance study of anaerobic metabolism of Escherichia coli.

Proton correlation nuclear magnetic resonance has been used to investigate anaerobic metabolism of glucose in Escherichia coli cells. The time course of the concentrations of six metabolites (ethanol, lactate, acetate, pyruvate, succinate, and formate) has been followed at the very early state of fermentation, and used to discuss dynamical aspects of the mixed-acid fermentation of glucose by E. coli.
