Question

Which of the following is not an advantage of impregnated wet beads?

(a) Protection of the contained enzyme

(b) More facile recovery of the biocatalyst

(c) Solvent polarity

(d) Allowing efficient and continuous use of biphasic PBRs

I got this question by my school teacher while I was bunking the class.

The question is from Recent Advances in section Recent Advances in Enzyme Technology of Enzyme Technology

Answer 1

The correct option is (c) Solvent polarity

The best I can explain: The advantages of impregnated wet beads are as follows:

* Protection of the contained enzyme at higher rates of stirring.

* Enabling more facile recovery of the biocatalyst.

* Allows to be used with low molecular weight hydrophilic coenzymes with the assistance of a coenzyme regenerating process.

* Allowing efficient and continuous use of biphasic PBRs as long as the moving organic phase is saturated with water.

Solvent polarity is one of the factors for the choice of the organic phase.
