Question

Which of the following is not true of solid state fermentation (SSF)?

(a) Easy downstream process

(b) Small-size bioreactors are used

(c) Greater chances of contamination

(d) Less consumption of energy

I got this question during a job interview.

I'm obligated to ask this question of Commercial Applications topic in chapter Commercial Applications of Fermentation of Fermentation Technology

Answer 1

Right choice is (c) Greater chances of contamination

The best I can explain: The chances of contamination is low because of less availability of water. However, the chances of contamination are more in submerged liquid fermentation. The consumption of energy is less for gas transfer and small-size bioreactors are used. The downstream processing is cheap, easy and time-saving.
