Basically it's a fancy word for high speed centrifugation. Modern ultracentrifuges can reach speeds resulting in 150,000x gravitational force (gs).
Centrifugation is the process of separating two immiscible liquids. The fluid which is above the sediment after centrifugation, is called the supernatant.
Bacterial cells cannot be lysed (or killed) through centrifugation alone. Although repeated centrifugation and resuspending will kill many bacterial cells as a result of shear stress on the cell membrane

Differential centrifugation: The solution (eg sucrose) is uniform throughout the test tube. You separate organelles based on their size and density.Density gradient centrifugation: There is a gradient of concentration of solution throughout the test tube. The concentration of sucrose is minimal at the top of the tube and maximal at the bottom of the tube. This type of centrifugation separates organelles by density only.
