Answer #1

During centrifugation, centrifugal force is applied & supernatant & pellet are separated due to principle of sedimentation. Due to the application of centrifugal force, substances with higher density move outward in the radial direction & substances with higher density move to the center. Pellet is the concentrated substances & due to their high density compared to the supernatant (Liquid phase) it comes to the bottom & supernatant comes to the top. As a result, we get two different phases.

A researcher withdraws 12 mL of culture 7 hours after inoculation, which has a cell concentration of 1.5 x 109 cells/mL. After centrifugation and discarding the supernatant, how much tryptone broth, in mL, should she use to resuspend the pellet to obtain a concentration of 3.5 x 109 cells/mL? The answer is 5.1 mL but need to show work.
