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.en1522-264020171217661772Wiley-VCH Verl.Escherichia coliMixing timeProcess engineering characterizationSpecific power inputStirred bioreactorVolumetric mass transfer coefficientTechnikIngenieurwissenschaftenJournal Article10.1002/cite.201700039Other
