Question

Which of the following is not an advantage of single-tank operation?

(a) Reduction in process time

(b) Avoids tank-to-tank transfer

(c) Avoids oxygen pick-up

(d) Avoids foam formation

This question was posed to me in homework.

I would like to ask this question from Large Capacity Fermenters topic in portion Fermentation System & Management of Fermentation Technology

Answer 1

Right choice is (d) Avoids foam formation

The best explanation: The avoiding of the formation of foam is an advantage of antifoaming agents or defoamers. The most important advantage of single-tank operation is the reduction in total process time, avoids tank-to-tank transfer and therefore avoiding the possibility of oxygen pick-up.
