For production of biotechnological product at manufacturing scale bioreactors are used for which all statements are correct except one.

A
The stirrer in tank bioreactors helps to mix the reactor contents and facilitates oxygen availability throughout the bioreactor
B
Sampling ports in bioreactors are meant for adding raw materials into them
C
Optimum condition for production of biotechnological product like pH, temperature etc. are monitored in them
D
Air bubbles bubbled through the reactor dramatically increase the oxygen transfer area

Solution:

Sampling ports are meant for discharging the spent broth for examining the extent of formation of recombinant protein by genetically modified organism or cells and extent of exhaustion of raw materials.
