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 ...

While the degree of the cell disruption decreased with increasing cell density in DynoMill and LabStar, the cell disruption in the MS 18 increased. Depending on processing parameters, more than 90% of algae cells were disrupted by passing through the bead mills and bacteria count in algae suspension was reduced to about two orders.
