Which of the following should be chosen for best yield if one were to produce a recombinant protein in large amounts?
a. Laboratory flask of largest capacity
b. A stirred-tank bioreactor without in-lets and out-lets
c. A continuous culture system
d. Any of the above
The answer is the option (c) A continuous culture system
