Question

What do you mean by ‘scale-down’?

(a) Decreasing the scale of fermentation

(b) Increasing the scale of fermentation

(c) Decreasing the rate of agitation

(d) Increasing the rate of fermentation

I have been asked this question in an online interview.

The doubt is from Aeration and Agitation topic in section Aeration and Agitation of Fermentation Technology

Answer 1

Right answer is (a) Decreasing the scale of fermentation

To explain I would say: Scale-up means decreasing the scale of fermentation. Decreasing the scale of fermentation involves the decrease in volume that is from large scale to small scale.
