Cell disruption is the process of breaking open (otherwise known as lysing) cells in order to obtain the intracellular fluid (commonly referred to as lysate). There are a variety of intracellular components that may be desired to obtain via cell disruption, including proteins and viral vectors that are not expressed extracellularly.

The disruption of yeast cell wall by bead mill was affected by impact of beads or paddles and has a possibility to destroy the very proteins being sought (Goldberg, 2015). Additionally, the formation of very fine cell debris and nonselective disruption result in increased downstream processing costs. So the method is not an ideal one for ...

This paper compares two deconvolution methodologies used to estimate residence time distributions (RTD) in industrial closedcircuit ball mills. Parametric and nonparametric deconvolution techniques were evaluated. Both techniques allowed for direct RTD estimates from inlet and outlet tracer measurements in the mills, with no need for mass balances nor assumptions to correct the effect of the ...

17. Cell disruption 17 Mechanical cell disruption methods •French press (pressure cell) and highpressure homogenizers. In these devices, the cell suspension is drawn through a check valve into a pump cylinder. At this point, it is forced under pressure (up to 1500 bar) through a very narrow annulus or discharge valve, over which the pressure drops to atmospheric.

Figure 1. Methods of microbial cell disruption (Geciova J., 2002) Different cells have different structures; hence they require different methods for disruption. Cell walls act as additional disruption deterrents, with yeast cells being particularly difficult to disrupt, as the cell wall limits the solvents access to the desired products.
