Question

Rotary drum tank reactor comes under which type of bioreactors?

(a) Mechanically agitated bioreactors

(b) Air driven bioreactors/Pneumatically agitated bioreactors

(c) Non-agitated bioreactors

(d) Wave bioreactors

This question was posed to me in unit test.

This interesting question is from The Story of Penicillin:How Biologists and Engineers Work Together in chapter Bioprocess Development of Bioprocess Engineering

Answer 1

The correct answer is (a) Mechanically agitated bioreactors

To explain I would say: Rotary drum tank reactor comes under Mechanically agitated bioreactors because it contains Stirrer paddle which provides efficient mixing and also causes production on a large scale.
