*Dry Cell Mass

a. Calculate the average cell mass yield factor, YX/S in this fermentation.

b. Calculate the maximum specific growth rate, mMAX, in the logarithmic growth phase.

c. Calculate the volumetric growth rate, dX/dt = rX at time=125 min.

d. Calculate the volumetric substrate utilization rate, rS, and the specific substrate utilization rate, qS, of the yeast at time = 170 min, assuming that the average yield factor can be used to determine rS.

e.Calculate the concentration of left over substrate at time = 130, again assuming that the average yield factor can be used.
