Question

What is the function of Pluronic f-68?

(a) To increase the foaming

(b) To decrease the foaming

(c) Increase cell attachment

(d) To change the composition of the cells

I had been asked this question at a job interview.

I'd like to ask this question from Role of Shear in Stirred Fermenters topic in division Fluid Flow and Mixing of Bioprocess Engineering

Answer 1

(b) To decrease the foaming

Pluronic F-68 is commonly used in bioprocessing to reduce foam formation and protect cells from shear stress in stirred fermenters. It acts as a surfactant, minimizing foam and helping maintain stable conditions for cell cultures.
