Multi-scale models for the optimization of batch bioreactors [PDF]

open access: yesChemical Engineering Science, 2012
Abstract Process models play an important role in the bioreactor design, optimisation and control. In previous work, the bioreactor models have mainly been developed by considering the microbial kinetics and the reactor environmental conditions with the assumption that the ideal mixing occurs inside the reactor.
