Question

Assertion: Floatation is an efficient technique to separate cells during downstream processing.
Reason: Bubbling of air through fermentation mix makes the biomass float on the surface along with foam.

• A. [A] is true and [R] is false.
• B. [A] is false and [R] is true .
• C. Both [A] and [R] are true and [R] is a correct explanation to [A].
• D. Both [A] and [R] are true but [R] is not a correct explanation to [A].

Answer 1

The correct option is C Both [A] and [R] are true and [R] is a correct explanation to [A].

Floatation is a technique used for cell separation. In this process air bubbles are pumped through the fermentation mix. This creates foam and along with it cells also come to the surface and float. These floating cells are easy to separate. This process is easy to perform as it does not involve any addition of chemicals.
