The efficiency of biomass production of Escherichia coli and the nitrogen balance of the aerobic culture system were studied in a nitrogen-limited medium where glutamic acid or ammonium sulfate was the sole source of nitrogen. The amount of bacterial-N at the stationary pbase was proportional to the amount of nitrogen added to the medium, and most of the nitrogen consumed was converted into cell material while a small amount was excreted as waste products. Chemical properties of the nitrogen in the waste products were affected both by the carbon source and by the pH of the medium. The dynamic equilibrium of nitrogen between the bacterium and the waste products was also discussed from the active reutilization of nitrogen in the waste products by the same bacterium.
