Question

The development of bioreactors is required to produced large quantities of
products.
(a) Give optimum growth conditions used in bioreactors.
(b) Draw a well labelled diagram of simple stirred, tank bioreactor.
(c) How does a simple stirred tank bioreactor differ from sparged stirred
tank bioreactor ?

Answer 1

(i) Temperature, pH, substrates, salts, vitamins and oxygen.
(ii) Figure 11.7(a) simple stirred-tank bioreactor Page No. 204 NCERT book, Biology-XII
(iii) The stirrer facilitates even mixing and oxygen availability throughout simple-stirred tank bioreactor, whereas in case of sparged stirred tank bioreactor, air is bubbled throughout the reactor for proper mixing.
