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 CHI.5500.31N0.25. The yield of biomass from glucose is measured at 0.48 g g^-1; the yield of recombinant protein from glucose is about 20% that for cells. If the biomass yield remains at 0.48 g g^{- l}, how much change in oxygen requirement for wild-type E. coli unable to synthesise recombinant protein?
