Q. Assertion: Flocculation is used for cell separation during downstream processing.
Reason: Density of cells remains same after flocculation.

1. [A] is true and [R] is false.
2. [A] is false and [R] is true .
3. Both [A] and [R] are true and [R] is a correct explanation to [A].
4. Both [A] and [R] are true but [R] is not a correct explanation to [A].

Q. 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.

2. Both [A] and [R] are true but [R] is not a correct explanation to [A].
3. [A] is true and [R] is false.
4. [A] is false and [R] is true .
