Assertion(A): In continuous culture system, (industrial fermentation) the used growth medium is drained out from one side, while fresh medium is added from other side.
Reason(R): Continuous culture maintains the microbial cells in their exponential growth phase.
1. Both (A) and (R) are true and (R) is the correct explanation of (A).
2. Both (A) and (R) are true but (R) is not the correct explanation of (A).
3. (A) is true but (R) is false.
4. Both (A) and (R) are false.
