Optimization of Bioethanol Ethanol Production in Fed-batch Fermentation
This study focuses on improving the productivity of a fed-batch ethanol fermentation process by developing and implementing in real time, an optimum feeding policy. A constraint-based stoichiometric model is developed using the systems biology approach, which can quantitatively predict the cellular behavior of the E coli strain, KO11. However, the predictions from this model are accurate under ...
متن کاملNonlinear Mpc for Recombinant Zymomonas Mobilis Fed-batch Ethanol Fermentation
This work presents the development of an unstructured kinetic model incorporating the differing degrees of product inhibition on the kinetic rates of recombinant Zymomonas mobilis fermentation. A mechanism for the inhibition of two competing substrates cellular uptake via membrane transport is proposed. The model was utilized in a nonlinear model predictive control (NMPC) algorithm to control p...
متن کاملFED-BATCH BIOREACTOR PROCESS WITH RECOMBINANT Saccharomyces cerevisiae GROWING ON CHEESE WHEY
Saccharomyces cerevisiae strain W303 was transformed with two yeast integrative plasmids containing Kluyveromyces lactis LAC4 and LAC12 genes that codify β-galactosidase and lactose permease respectively. The BLR030 recombinant strain was selected due to its growth and β-galactosidase production capacity. Different culture media based on deproteinized cheese whey (DCW) were tested and the best ...
متن کاملModelling 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 کاملKinetic study of batch and fed-batch enzymatic saccharification of pretreated substrate and subsequent fermentation to ethanol
BACKGROUND Enzymatic hydrolysis, the rate limiting step in the process development for biofuel, is always hampered by its low sugar concentration. High solid enzymatic saccharification could solve this problem but has several other drawbacks such as low rate of reaction. In the present study we have attempted to enhance the concentration of sugars in enzymatic hydrolysate of delignified Prosopi...
