Production of recombinant protein by a geneticallyengineered strain of Escherichia coli is proportional to cell growth. Ammonia is used as nitrogen source for aerobic respiration of glucose. The recombinant protein has an overall formula CH_I.550_0.31N_0.25. The yield ofbiomass from glucose is measured at 0.48 g g^-1; the yield of recombinant protein from glucose is about 20% that for cells. How much ammonia is required per gmol glucose?
