Question

Which of the following uses the membrane to concentrate cell suspension?

(a) Cepa Z41

(b) Watson Marlow 501

(c) Filtration

(d) Autoclude V8

This question was addressed to me in an interview.

This is a very interesting question from Fermentation Laboratory in division Equipping a Fermentation Laboratory, the Design and Preparation of Media for Bioprocesses of Fermentation Technology

Answer 1

The correct answer is (c) Filtration

For explanation I would say: Filtration uses the membrane to concentrate the cell suspension. It is also known as tangential flow filtration. Cell washing can also be done through cross-flow filtration before centrifugation, although the process is time-consuming.
