Both Saccharomyces cerevisiae yeast and Zymomonas mobilis bacteria produce ethanol from glucose under anaerobic conditions without external electron acceptors. The biomass yield from glucose is 0.11 g g-1 for yeast and 0.05 g g-I for Z. mobilis. In both cases the nitrogen source is NH3. Both cell compositions are represented by the formula CH1.800.5N0.2. What is the yield of ethanol from glucose by Saccharomyces cerevisiae yeast?

#Section 5: Bioprocess Engineering and Process Biotechnology
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 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?

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?
