“…In general, the viability of microorganisms decreases with increasing compression stress [ 7 , 8 , 9 , 18 , 19 , 20 , 21 , 22 , 23 , 24 , 25 , 26 , 27 , 28 ]. However, previous data on the survival of microorganisms during tableting exist predominantly for lyophilized microorganisms [ 9 , 18 , 19 , 20 , 21 , 22 , 27 , 29 , 30 , 31 , 32 , 33 , 34 , 35 , 36 , 37 , 38 ] and are hardly available for fluidized bed granulated ones; however, at least some data are available for wet granulated and, e.g., oven-dried microorganisms [ 7 , 8 , 23 , 24 , 25 , 39 , 40 ]. Considering, especially, the different product structures (physical mixture vs. granules and the typically high porosity and fragility of lyophilized products), the survival during tableting needs to also be addressed for granulated microorganisms.…”
