The control of fed-batch fermentation processes—A survey

Automatica, 1987
A survey of the control of fermentation processes operated in fed-batch mode is presented. Truely optimal conditions can only be found by minimizing (or maximizing) a cost criterion subject ot the constraints imposed by a mathematical model of the process.

Kinetics of Enzymatic Hydrolysis of Olive Oil in Batch and Fed-batch Systems

Applied Biochemistry and Biotechnology, 2014
This work reports experimental data, kinetic modeling, and simulations of enzyme-catalyzed hydrolysis of olive oil. This reaction was performed in batch system and an ordered-sequential Bi Bi model was used to model the kinetic mechanism. A fed-batch system was proposed and experimental data were obtained and compared to the simulated values.

Modeling of Overflow Metabolism in Batch and Fed-Batch Cultures of Escherichia coli

Biotechnology Progress, 1999
A dynamic model of glucose overflow metabolism in batch and fed-batch cultivations of Escherichia coli W3110 under fully aerobic conditions is presented. Simulation based on the model describes cell growth, respiration, and acetate formation as well as acetate reconsumption during batch cultures, the transition of batch to fed-batch culture, and fed ...

An analysis of extended and exponentially‐fed‐batch cultures

Biotechnology and Bioengineering, 1977
AbstractUnder certain conditions it is shown that an extended culture is equivalent to an exponentially‐fed‐batch culture, that an exponentially‐fed‐batch culture (and an extended culture) can be maintained at a steady state and that an exponentially‐fed‐batch culture may be mimicked by a continuous‐flow culture with a constant dilution rate ...

Fed-Batch Culture Processes

2020
The cells used in cell culture processes are all derived from animals. Their genetic and epigenetic control circuits and their physiology have evolved to carry out the physiological functions of the tissue from which they were derived, not to sustain themselves and proliferate in in vitro culture.

Use of surface‐immobilized Trichoderma in batch and fed‐batch fermentations

Biotechnology and Bioengineering, 1988
AbstractNeedle‐punch polyester was shown to be an effective support material for the immobilization of Trichoderma reesei Rut C30. When used as a resident inoculum for a batch process, the immobilized Trichoderma was very stable and resulted in a reduced rate of biomass generation in the bulk liquid phase as compared to cultures inoculated with free ...

Modelling of batch and fed-batch ethanol fermentation

2016
Two series of batch and fed-batch fermentations were carried out using S.cerevisiae in a semi-defined medium containing 200 gl-1 glucose as limiting substrate. Growth rates were calculated and the data used to test the applicability of eight empirical kinetic models.

Fed-batch and continuous culture

1990
Abstract A variety of techniques has been developed for the submerged culture of microorganisms. Batch and fed-batch culture have been part of the art of fermentation since antiquity and are still used today for most industrial fermentations.
