Biological processes have become widely used in the industry for the last couple of decades, with different purposes: either to produce some biochemical compounds synthesized by a microorganism (e.g., alcoholic fermentation etc.), to cultivate a biomass for its utilization (e.g., baker’s yeast etc.) or extraction of its metabolites (e.g., carotene from plankton etc.), or to degrade a pollutant (e.g., wastewater treatment etc.). Therefore, bioreactors require advanced regulation and control procedures to ensure good performances of the bioprocesses due to the increasing demand on quality, productivity as well as environmental responsibilities. However, the control of bioreactors is a delicate problem since most of the time the available biological models are only rough approximations. Indeed, biological systems are known to be highly variable and difficult to measure since, no reliable biological law is available. Apart from that, it is also well known that the biomaterials used in some bioprocesses are costly and require a stringent control over product formation, as in animal cell culture.
Since, animal cell membrane is known to be very sensitive to the shear stress (e.g., Continuous Stirred Tank Reactor (CSTR), bubble column reactor etc.), need for the development of an alternative bioreactor is realized. In the present investigation, the attention has been paid to the applicability of an alternative and newly developed novel “Sea-Saw” bioreactor keeping the above in mind. The gentle “Sea-Saw” motion of substrate liquid in the developed reactor provides enough scope for oxygen absorption to maintain optimum cell mass growth.
The present work in this thesis may broadly be classified into two parts. One arena covers the mechanical aspects of the bioreactor’s working principle and scope of necessary design modifications/improvements. Particular emphasis has been put on the dynamics of the see-saw movement, shear force constraint on the fluid motion and oxygen intake of the bioreactor. Keeping in view that the dissolved oxygen is the single most important process variable for measurement and control in an aerobic bio-reaction process, a low cost dissolved oxygen sensor has also been developed.
The second part of the present work deals with the practical implementation and unification of several process parameters of the newly developed bioreactor. For the acquisition, monitoring and control of process variables (e.g., pH and temperature of the bioreactor fluid, etc.) through a personal computer (PC), an object oriented program including the graphical user interface (GUI) has been developed in the MS Visual Basic platform. A MATLAB Simulink program has been employed for simulation of the bio-reaction process. The GUI devised for instrumentation and control of the bioreactor provides flexibility to the user for both manual and auto mode operations. Although, the measurement of other process variables like cell mass and substrate concentrations requires continuous monitoring but, these are done off-line by collecting samples and analyzing them carefully.
The modeling of bioprocess is known to be immensely complicated in general. In the present study, a simple lumped, unstructured and unsegregated model developed from material balance principle has been used. This model assumes homogeneity of the fluid medium inside the bioreactor for which the time tested Monod’s growth model has been considered. Another elegant predator-pray type approach has been sought to be developed for modeling aerobic bioprocesses where cell growth takes place by consuming double substrate (i.e., the nutrient and oxygen). A sliding mode observer has been devised for the soft-sensing of the bioprocess variables to reduce the experimental cost/time considerably.
To check the efficiency and viability of the present approach, good numbers of carefully chosen experimental results on yeast growth in the see-saw bioreactor are presented finally.
