An in 2016 published DECHEMA guideline concerning process engineering characterization and a new Escherichia coli model process were utilized for the qualification of two geometrically similar stirred stainless steel bioreactors (30 L and 100 L working volume). The achieved results demonstrate that performing an additional biological model process is a valuable complement to the process engineering characterization. Optical densities of 27 (100 L) and 39 (30 L) were reached in the batch cultivation process.
