Bead mill has been shown to be one of the most effective ways for mechanical disruption of microbial cell walls and has been a subject of continuing research interest for the past two decades. Bead mill can achieve high disruption efficiency in a singlepass operation with good temperature control, easy scaleup procedure and low labour intensity.

Intracellular products such as recombinant insulin, which are typically produced in microbial host cells, demand a product release step to remove them from the cell. How this is performed determines the quantity of released contaminants, the particle size distribution of cell debris and the physical properties of the resultant process stream, which all impact on the performance of the ...
