Saccharomyces cerevisiae produces high biomass yields at low glucose concentrations and high dissolved oxygen concentrations. Which of the following should be followed for maximizing its biomass productivity?
Options
A. Batch fermenter with a high initial glucose concentration
B. Continuous fermenter with a low initial glucose concentration
C. Fed batch fermenter
D. All of the above

Options
A. always decrease with dilution rate
B. increase with dilution rate until washout
C. remain constant irrespective of the dilution rate
Correct Answer: decreases the productivity of the fermenter
4. The cellular productivity in a continuous stirred tank fermenter (CSTF) increases with an increase in the dilution rate and reaches a maximum value. If the dilution rate is increased beyond the maximum point, the productivity will
