TOPIC 5.3: BIOREACTOR DESIGN AND CONTROL

Question 1

Fermenter

Answer 1

1) An enclosed and sterilized vessel that maintains optimal conditions for the growth of a microorganism

2) The microorganism undergoes fermentation to produce large quantities of a desired metabolite for commercial use.

3) It also can be used to cultivate of microbial plant and animal cell

4) Can be aerobic or anaerobic

Question 2

Function of fermenter

Answer 2

 Main function of a fermenter is to provide a controlled environment for the growth of a microorganism to obtain a desired product.

 Fermenter should be capable for being operated aseptically for a number of days and should be
reliable in long-term operation.

 For aerobic fermentation, adequate aeration and agitation should be provided to meet the metabolic
requirements of the microorganism. However, the mixing should not cause damage to the microorganism.
