Question
Consider the microbial conversion of glucose to L-glutamic acid, as shown below. Assume that
initially the bioreactor contains 200 kg of glucose, 15 kg of ammonia and 54 kg of O2.
C6H1206 + NH3 +1.5 O2 →C5H9NO4+ CO2 + 3H2O
glucose
ammonia
glutamic acid
a) Which reactant is limiting?
b) What is the percentage excess of the other reactants?
c) If the reaction proceeds to completion, how much of the excess reactants will be left; how
much L-glutamic acid will be formed; and what is the extent of reaction ?
d) If the reaction proceeds to a point where the conversion of the limiting reactant is 33%, how
much of each reactant and product is present at the end, and what is the extent of reaction E ?
e) If the reaction proceeds to a point where 35 kg of O2 is left, what is the fractional conversion of
glucose? What is the fractional conversion of O2? What is the extent of reaction E ?
