Question

KLa is measured in the absence of microorganisms?

(a) True

(b) False

This question was addressed to me in an international level competition.

This is a very interesting question from Measurement of KLa topic in chapter Mass Transfer of Bioprocess Engineering

Answer 1

Right choice is (a) True

To explain I would say: The methods to measuring the kLa in a microbial bioprocess can be classified into the absence of microorganisms or with dead cells and in the presence of biomass that consumes oxygen at the time of measurement.
