Abstract
Results are presented which show how the microcarrier concentration affects the hydrodynamic environment in animal cell bioreactors. At low levels of agitation, no physical effects of microcarrier concentration were found. However, cell growth was strongly influenced by cell concentration. At high levels of agitation, a strong detrimental effect of microcarrier concentration was found. A new mechanism of hydrodynamic damage was identified which is second order in microcarrier concentration. The identification of this mechanism adds to the fundamental understanding of hydrodynamic phenomena in microcarrier bioreactors.
