Question 2:
47 grams of glucose was allowed to ferment using S. cerevisiae strain to form ethanol and carbon dioxide. 15.3 grams of ethanol was recovered by distillation at 25oC
- Calculate what would be theoretical maximum yield
- Calculate what was the percent yield
- How much volume of CO2 was produced
- What would be the % of ethanol if the volume of the bioreactor was 300 ml
- What is the most common fermenter used to produce beer in industry?

2. From your glucose data, a. From your results table and question 1, how many moles of glucose were consumed assuming all the gas produced was carbon dioxide resulting from the breakdown of glucose? From this, what was the mass of glucose actually used by the yeast in your experiment? Calculate the percentage of glucose used? Do you think the lack of glucose affected the rate of CO2 generation? (1pts.) b. In the experimental set up, the generated ethanol remains...

Metabolic Pathway Engineering Problem Set 5 Engineering a Fermentation System: Fermentation of plant matter to produce ethanol for fuel is one potential method for reducing the use of fossil fuels and thus the CO2 emissions that lead to global warming. Many microorganisms can break down cellulose then ferment the glucose to ethanol. However, many potential cellulose sources, including agricultural residues and switchgrass, also contain substantial amounts of arabinose, which is not as easily fermented. Escherichia coli is capable of fermenting...
