Question

In-situ or on-line measurement is appropriate for biomass analysis in fermentation.

(a) True

(b) False

The question was asked in an interview.

Origin of the question is Monitoring and Control of Bioreactors in chapter Reactor Engineering of Bioprocess Engineering

Answer 1

The correct answer is:

(a) True

In-situ or online measurement is indeed appropriate for biomass analysis in fermentation processes. These methods allow real-time monitoring of biomass concentration without disrupting the fermentation process. In-situ measurements, such as optical density or capacitance-based sensors, can continuously track the growth of microorganisms, providing crucial data for optimizing bioreactor conditions and ensuring efficient fermentation.
