In this work, the dissipative nature of spatially distributed
bioprocess systems is exploited to develop efficient state
observers based on a low dimensional dynamic representation of
the original set of partial differential equations. The approach
we suggest combines standard observer design techniques
for bioreactors with efficient model reduction methodologies
based on projection of the original concentration fields on
low dimensional subspaces capturing the slow dynamics of the
Aspects related with the location of sensors and their influence
on the ability to reconstruct concentration fields will also
be considered. Finally, the different aspects of the methodology,
as well as the efficiency of the resulting observers will be
illustrated on a case study of industrial interest, namely a
tubular bioreactor producing gluconic acid by Aspergillus Niger.
