Question

Which sort of Fermenter is used for production of Penicillin?

(a) Batch Fermenter, Fed-Batch Process

(b) Fed-Batch Fermenter, Fed-Batch Process

(c) Continuous Batch Fermenter , Fed-Batch Process

(d) Fed-Batch Fermenter, Batch process

This question was addressed to me in an interview for job.

My doubt stems from Aerobic Bioprocesses topic in portion Mixed Cultures & Traditional Industrial Bioprocesses of Bioprocess Engineering

Answer 1

The correct option is (a) Batch Fermenter, Fed-Batch Process

To explain I would say: For Large production of Penicillin a Batch Fermenter, and a Fed-Batch Process  is normally used to prolong the stationary period and so as to increase the production of Penicillin and Batch is used over continuous fermenter for large scale production and fed-batch process is used to overcome its disadvantages.
