Bioprocess and Fermentation Monitoring

The production of fuels and chemicals from lignocellulosic biomass demands efficient processes to compete with fossil fuel-derived products. Key biorefinery processes, such as enzymatic hydrolysis of cellulose and microbial fermentation, can be monitored by advanced sensors in real time, providing information about reactant and product concentration, contamination, and reaction progress. Spectroscopic techniques such as Raman spectroscopy provide a means of quickly and accurately assessing many types of reaction mixtures non-destructively, in real time, and with no costly sample preparation and analysis time. Raman spectroscopy techniques have been developed to accurately quantify a number of compounds present in lignocellulosic processes, and methods have been developed to overcome the presence of fluorescent compounds that can increase the spectral background. Online Raman sensors also can provide the feedback measurements necessary for advanced process controls APCs. Specifically, model predictive control, a common APC used extensively throughout similar processing industries, is especially well suited for ensuring optimal production of bio-based chemicals from lignocellulosic material.

Recent advances in analytical instrumentation, biosensors and computer technology have lead to the development of new approaches and techniques to control and optimize bioprocesses. Use of on-line measurements to monitor bioprocesses for identifying physiological state of cells and controlling environmental conditions to maintain the cells in the optimal physiological state has become more prevalent. Novel control strategies, along with new concepts, such as expert systems and artificial neural networks have been introduced and applied in bioprocess monitoring and control.

Over the past decade, the application of chemical optical sensors for bioprocess monitoring has gradually taken roots. Constant further development of this measurement technology and the possibility to manufacture such sensors in various designs even for single-use applications have led to new state-of-the-art devices for the biotechnology sector. Chemical optical sensors enable in situ, real-time monitoring of important culture parameters without sampling and therefore without disturbing a culture. Implementing this technology can decrease workloads and deepen knowledge about bioprocesses. In many culture environments and vessel formats, application of electrodes would be very cumbersome or impossible.

The advancement of bioprocess monitoring will play a crucial role to meet the future requirements of bioprocess technology. Major issues are the acceleration of process development to reduce the time to the market and to ensure optimal exploitation of the cell factory and further to cope with the requirements of the Process Analytical Technology initiative. Due to the enormous complexity of cellular systems and lack of appropriate sensor systems microbial production processes are still poorly understood. This holds generally true for the most microbial production processes, in particular for the recombinant protein production due to strong interaction between recombinant gene expression and host cell metabolism. Therefore, it is necessary to scrutinise the role of the different cellular compartments in the biosynthesis process in order to develop comprehensive process monitoring concepts by involving the most significant process variables and their interconnections.
