Cell Disruption
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.Web

Typical pressures used to disrupt yeast are 8,000 to 10,000 psi and several passes through the press may be required for high efficiency of disruption. Generally, the higher the pressure, the fewer the passes. Pressure cells rated at 20,000 psi maximum come in capacities of 3.7 and 35m1 and there is also a 35m1 capacity cell rated at 40,000 psi.Web
