Stability analysis of two linear distributed parameter bioprocess models

This paper proposes to extend the dynamical analysis results on chemical tu bular reactors presented in [5] to two linear distributed parameter models. These are in particular the linearized tangent models of two typical biopr ocess models: a basic tubular bioreactor model, and a denitrifying biofilte r model. The tools used for the analysis are those of the infinite dimensio nal system theory (e.g., [2]). In the paper we show the existence of soluti ons for the studied models, and emphasize stability conditions.
