Bacterial Cell Disruption by Bead Beating. Bacteria can be easily disrupted by treatment with enzymes and detergents. For gram positive organisms, removing the cell wall and then lysis by the addition of SDS or similar detergent are suitably early steps in isolating nucleic acids.

Bead Mills - SolidsWiki

Bead Mills are one of the many technologies used for grinding, lysing and homogenization of laboratory samples. Bead Mills are typically used for samples that are difficult to disrupt with standard mechanical laboratory homogenizers. These sample types include tumor, heart, e-coli, yeast, bone, skin, cartilage, spores, seeds and soil.
