Question

Which instrument is used to measure growth kinetics of plant cell lines?

(a) Rheometry

(b) Spectometry

(c) Mass spectrometry

(d) Conductometry

The question was asked during a job interview.

I'd like to ask this question from Production Kinetics in Cell Culture topic in division Homogenous Reactions of Bioprocess Engineering

Answer 1

Right option is (d) Conductometry

To elaborate: The conductivity method of measuring growth kinetics of plant cell lines was used especially with the purpose of bioprocess engineering applications of plant cell cultures. The major advantages of using conductometry as the biosensing technique for measurement of plant cell growth kinetics are:

i) The method is very economical and efficient

ii) It gives accurate, reliable and reproducible measurements, while amenable to continuous online monitoring and process control.

iii) It is a noninvasive method which does not adversely affect the plant cells or the bioreactor operation.
