Disruption of microbial cells for intracellular products

Mechanical cell disruption Both solid shear (e.g. bead mill) and liquid shear (e.g. high- pressure homogenizer) based methods of cell disruption have proven successful on a large scale. The solid shear methods may involve either a grinding action as in a ball mill or may involve extrusion of frozen cells, either alone

Bead-Mill Disruption of Biological Samples - HSE•AG

In medium- to high-throughput workflows, bead-mill technology has proven to be an efficient method for disruption and homogenization of tissue samples and other biological materials. The mechanical disruption is the result of high-speed shaking of samples mixed with stainless steel, tungsten, carbide or glass beads, thereby beating and grinding the samples until they are sufficiently disrupted.

Cell Disruption - an overview ScienceDirect Topics

Cell disruption can be brought about by a high-speed bead mill, consisting of a series of rotating discs and a charge of glass ballotini (Figure 2).The cell suspension is agitated at a very high speed. The mill chamber is almost full of grinding beads during operation, with the optimum concentration of ballotini usually being 70–90% of the volume of the chamber.

Bead Mills - SolidsWiki

Typically, a higher volume ratio of beads to cells produces a faster rate of cell disruption. After the processing cycle is complete, the beads settle by gravity in the vessel and the resulting homogenate is easily removed by pipette. Bead Mills are relatively cross-contamination free because of the disposable beads and sample tubes they employ.
