(a) Minimum reaction time

(b) Cheap isolation of cells/enzymes

(c) Can be reused

(d) Less labour input

This question was posed to me during an interview.

The origin of the question is Fermentation System in portion Fermentation System & Management of Fermentation Technology

Answer 1

The correct choice is (b) Cheap isolation of cells/enzymes

The explanation: The advantages of immobilization of cells or enzymes are that it can be reused, and less labour input is required. The reaction time is also less and it is a continuous process but cost for isolation, purification of cells or enzymes is high.
