1. A bioreactor is a vessel in which biological conversion is carried out involving enzymes, microorganisms, and/or animal and plant cells. In the anaerobic fermentation of grain, the yeast Saccharomyces cerevisiae digests glucose (C6H₁2O6) from plants to form the product ethanol (C₂H5OH) and propenoic acid (C₂H³CO₂H) by the following overall reactions: Reaction 1: C6H₁2O6 → 2 C₂H5OH + 2 CO₂ 12 Reaction 2: C6H₁2O6 → 2 C₂H3CO₂H + 2 H₂O In a batch process, a tank is charged with 4000 kg of a 12% solution of glucose in water. After fermentation, 120 kg of CO₂ are produced and 90 kg of unreacted glucose remains in the broth. What are the weight (mass) percent of ethanol and propenoic acid in the broth at the end of fermentation process? Assume that none of the glucose is assimilated into the bacteria.

Transcribed Image Text:1. A bioreactor is a vessel in which biological conversion is carried out
involving enzymes, microorganisms, and/or animal and plant cells. In
the anaerobic fermentation of grain, the yeast Saccharomyces
cerevisiae digests glucose (C6H₁2O6) from plants to form the product
ethanol (C₂H5OH) and propenoic acid (C₂H³CO₂H) by the following
overall reactions:
Reaction 1: C6H₁2O6 → 2 C₂H5OH + 2 CO₂
12
Reaction 2: C6H₁2O6 → 2 C₂H3CO₂H + 2 H₂O
In a batch process, a tank is charged with 4000 kg of a 12% solution of
glucose in water. After fermentation, 120 kg of CO₂ are produced and
90 kg of unreacted glucose remains in the broth. What are the weight
(mass) percent of ethanol and propenoic acid in the broth at the end of
fermentation process? Assume that none of the glucose is assimilated
into the bacteria.
