Eliminates foam generated during the process Choose the c

Options

  1. AA - II, B - IV, C - I, D - III
  2. BA - IV, B - II, C - III, D - I
  3. CA - IV, B - I, C - II, D - III
  4. DA - IV, B - II, C - I, D - III

Correct answer

D. A - IV, B - II, C - I, D - III

Step-by-step solution

A stirred-tank bioreactor has several components to maintain optimal conditions for microbial growth. The foam control system eliminates foam generated during the process (A-IV). The stirrer facilitates even mixing and oxygen availability throughout the bioreactor (B-II). The acid/base control system regulates the pH of the culture (C-I). Sampling ports allow the periodic withdrawal of small culture volumes for testing (D-III). Therefore, the correct match is A-IV, B-II, C-I, D-III. Answer: A - IV, B - II, C - I, D
