Question

Match the following.\[ \begin{array}{|c|l|c|l|} \hline & \textbf{List-I} & & \textbf{List-II} \\ \hline A & \text{Batch} & I & \text{Steady-state Operation} \\ B & \text{Fed-batch} & II & \text{Substrate Feeding Without Outflow} \\ C & \text{Continuous} & III & \text{No Input or Output} \\ D & \text{Chemostat} & IV & \text{Constant Dilution Rate} \\ \hline \end{array} \]

The correct matching is

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

Hint:

Fermentation processes: \[ \boxed{ \begin{aligned} \text{Batch} &\rightarrow \text{Closed system} \text{Fed-batch} &\rightarrow \text{Feed only} \text{Continuous} &\rightarrow \text{Steady state} \text{Chemostat} &\rightarrow \text{Constant dilution rate} \end{aligned} } \]

Answer 1

The Correct Option is A

Step 1: Recall the characteristics of each fermentation process. \[ \boxed{ \begin{aligned} \text{Batch} &\rightarrow \text{No input or output during operation} \text{Fed-batch} &\rightarrow \text{Substrate added without product outflow} \text{Continuous} &\rightarrow \text{Steady-state operation} \text{Chemostat} &\rightarrow \text{Constant dilution rate} \end{aligned} } \]

Step 2: Match List-I with List-II. Thus, \[ \boxed{ A-\mathrm{III},\; B-\mathrm{II},\; C-\mathrm{I},\; D-\mathrm{IV} } \] Therefore, \[ \boxed{(A)} \] is the correct answer.
