Question

Who claimed that oxygen balance technique is suitable for only small-scale fermenters?

(a) Cooper

(b) Humphrey

(c) Wang

(d) Taguchi

This question was addressed to me during a job interview.

My enquiry is from Aeration and Agitation topic in portion Aeration and Agitation of Fermentation Technology

Answer 1

The correct option is (c) Wang

Easiest explanation: Wang et al. in 1979 claimed that oxygen balance technique is suitable for only small-scale fermenters because, at a large-scale, the difference in dissolved oxygen concentration may be up to a larger extent with inlet and outlet gases.
