Question 21 pts

A In continuous culture, the net specific growth rate of the organism:

B is equal to the flow rate

C is equal to the dilution rate

D is greater than the dilution rate when cell recycle is introduced

E is equal to the growth rate minus the death rate

Question 31 pts

What is the optimal dilution rate (h-1) for the growth of E. coli in continuous culture, assuming the following:

- substrate limited growth

- no endogenous metabolism

- follows Monod growth kinetics

um = 0.4 h-1

Ks = 1.5 g/L

Yx/s = 0.5 g biomass/g glucose

So = 10 g/L glucose

Xo = 0 g/L

F = 100 L/h

VR = 1000 L
