Modelling of a Fed-Batch Fermentation Process
This report describes the building of a simulator for prediction of the dissolved oxygen concentration, the oxygen transfer rate and the concentration of carbon dioxide in a fermentation process. The steady state models were made using the linguistic equations method. The dynamic models were made using Simulink ® toolbox in the Matlab ® . At the beginning, some basics about fermentation and mic...
متن کاملMetabolic engineering of Corynebacterium glutamicum for cadaverine fermentation.
Cadaverine, the expected raw material of polyamides, is produced by decarboxylation of L-lysine. If we could produce cadaverine from the cheapest sugar, and as a renewable resource, it would be an effective solution against global warming, but there has been no attempt to produce cadaverine from glucose by fermentation. We focused on Corynebacterium glutamicum, whose L-lysine fermentation abili...
متن کاملAnaerobic growth of Corynebacterium glutamicum via mixed-acid fermentation.
Corynebacterium glutamicum, a model organism in microbial biotechnology, is known to metabolize glucose under oxygen-deprived conditions to l-lactate, succinate, and acetate without significant growth. This property is exploited for efficient production of lactate and succinate. Our detailed analysis revealed that marginal growth takes place under anaerobic conditions with glucose, fructose, su...
متن کاملBatch-to-Batch Iterative Learning Control of a Fed-batch Fermentation Process Using Incrementally Updated Models
Batch-to-batch iterative learning control of a fed-batch fermentation process using batchwise linearised models identified from process operation data is presented in this paper. Due to model-plant mismatches and the present of unknown disturbances, off-line calculated control policy may not be optimal when implemented to the real process. The repetitive nature of batch process allows informati...
متن کاملModeling the Fermentative Production of L-glutamic Acid by Corynebacterium Glutamicum in a Batch Bioreactor
The fermentation kinetics of L-glutamic acid by Corynebacterium glutamicum was studied in a batch bioreactor. Mathematical model using the logistic equation for growth, Leudeking-Piret kinetic equation for product formation and Leudeking-Piret like equation for substrate consumption was proposed. Based on the analysis of experimental data followed by computer simulation, the model seemed to pro...
