Production of recombinant protein by a genetically engineered strain of E.Coli is proportional to cell growth. Ammonia is used as nitrogen source for aerobic respiration of glucose. The recombinant protein has an overall formula CH155O31N25. The yield of biomass from glucose is measured at 0.48 g/g; the yield of recombinant protein from glucose is about 20% that for cells.(a)How much ammonia is required?(b)What is the oxygen demand?
