Question

“The productivity of the continuous culture must be greater than the batch”.

(a) True

(b) False

The question was asked in an interview.

This interesting question is from Comparison of Batch and Continuous Culture in Industrial Processes topic in division Microbial Growth Kinetics of Bioprocess Engineering

Answer 1

Correct choice is (a) True

Easiest explanation: The productivity in batch culture is at its maximum only towards the end of the process.

For a continuous culture operating at the optimum dilution rate, under steady – state conditions, the productivity will be constant and always maximum. Thus, the productivity of the continuous culture must be greater than the batch.
