The Control of Fermentation Processes
IFAC Proceedings Volumes, 1985Abstract A survey of the control of fermentation processes operated in fed-batch mode is Presented. Truely optimal conditions can only be found by minimizing for maximizing) a cost criterion subject to the constraints imposed by a mathematical model of the process. This approach leads to the design of a tracking controller, or servomechanism as it is

Coffee fermentation process: A review
Food Research International, 2023In recent years, the importance of controlling coffee fermentation in the final quality of the beverage has been recognized. The literature review was conducted in the Science Direct and Springer databases, considering studies published in the last ten years, 74 references were selected.

Recycle in fermentation processes
Biotechnology and Bioengineering, 1982AbstractUntil recently, the recycle of the solid (microbial), liquid, or gaseous phases in microbiological processes has only been practiced rarely, with the notable exception of activated sludge processes for wastewater treatment, where recycling of a large fraction of the microbial phase is essential for process stability and performance.

Fermentation and Post-fermentation Processing
1997Fermentation is one of the oldest methods of food preservation. The hygenic value of wine, as an alternative to local water supplies, has been known since well before the crusades. Although the interactive effects of ethanol, low pH, and the presence of preservatives have generally been credited for the antimicrobial properties of wine, recent research

Fermentation monitoring and process control
Current Opinion in Biotechnology, 1997The use of modern analytical online methods such as two-dimensional fluorescence measurements gives new insights into bioprocesses. With the resulting data, it is not only possible to better understand and document, for example, biotransformations, but also to develop efficient control strategies that lead to better productivity and lower costs.

Software sensors for fermentation processes
Bioprocess and Biosystems Engineering, 2007Four software sensors based on standard on-line data from fermentation processes and simple mathematical models were used to monitor a number of state variables in Escherichia coli fed-batch processes: the biomass concentration, the specific growth rate, the oxygen transfer capacity of the bioreactor, and the new R(O/S) sensor which is the ratio ...

Fermentation monitoring and process control
Current Opinion in Biotechnology, 1994During the past year, several papers describing the potential of new sensor devices for application in real bioprocesses have been published. Biosensors, optical sensors, and immunosensors are all gaining in importance. At present, the development of correct/adequate interfacing of biosensors to bioprocesses is the major limitation on progress.

Monitoring and Diagnosis of Fermentation Processes
2000This chapter deals with monitoring and diagnosing a fedbatch fermentation process by means of a real-time expert system. The first part of the chapter presents the rule-based expert system BIOTECH which, among other tasks, detects the abnormalities in the process behaviour beforehand, advises the operator about what to do to correct unwanted behaviours

Optimal control of a fermentation process
2003 European Control Conference (ECC), 2003This paper includes the description of a batch beer fermentation process that has been optimised using a technique based on the application of calculus of variations. The gradient method in function space is thus introduced as a valuable tool for the optimal control of the beer fermentation process selected.
