Question

Given below is a graphical representation of the scale-up window. What do the x and y-axis denote?

(a) y – agitation, x – aeration

(b) y – aeration, x – agitation

(c) y – KLa, x – time

(d) y – time, x – KLa

This question was addressed to me in semester exam.

This interesting question is from Aeration and Agitation in chapter Aeration and Agitation of Fermentation Technology

Answer 1

Correct option is (a) y – agitation, x – aeration

To explain: The x-axis denotes aeration and y-axis denotes agitation. The graph shows the ‘scale-up’ window defining the operating boundaries for aeration agitation in the scale-up fermentation.
