Enzymatic production of lactulose by fed-batch and repeated fed-batch reactor

Bioresource Technology, 2021
The effects of the most significant operational variables on reactor performance of fed-batch and repeated fed-batch were evaluated in the lactulose production by enzymatic transgalactosylation. Feed flowrate in the fed stage (F) and fructose to lactose molar ratio (Fr/L) were the variables that mostly affected the values ​​of lactulose yield (YLu ...

Control of fed-batch fermentations

Biotechnology Advances, 1999
Fed-batch fermentation is used to prevent or reduce substrate-associated growth inhibition by controlling nutrient supply. Here we review the advances in control of fed-batch fermentations. Simple exponential feeding and inferential methods are examined, as are newer methods based on fuzzy control and neural networks.

Fed-batch culture technology

Biotechnology Advances, 1986
The use of fed-batch procedures offers distinct advantages over other modes of operation of bioreactors, and is a widely researched technique. These advantages are discussed; some uses of fed-batch procedures and the associated methods of modelling and control are reviewed.

Dynamic reoptimization of a fed‐batch fermentor

Biotechnology and Bioengineering, 1999
Traditionally, fed-batch biochemical process optimization and control use complicated models and off-line optimizers with no on-line model adaptation and re-optimization. This work demonstrates the applicability, effectiveness, and economic potential, of a simple phenomenological model for modeling, and a novel optimizer for on-line re-optimization and

Calorimetric control of fed‐batch fermentations

Biotechnology and Bioengineering, 1990
AbstractMeasurements of the heat produced by Saccharomyces cerevisiae CBS 426 were used in conjunction with elemental and enthalpic balances to control fed‐batch fermentations. A proportional control using the ratio of carbon dioxide evolution rate to heat production resulted in high biomass yields and minimal ethanol production.

Batch and Fed‐Batch Degradation of Enrofloxacin by the Fenton Process

Chemical Engineering & Technology, 2017
AbstractEnrofloxacin is a synthetic second‐generation fluoroquinolone used as an antimicrobial agent exclusively in veterinary medicine. To simulate the treatment of wastewater contaminated by enrofloxacin, four‐day long fed‐batch runs were carried out according to the Fenton process with an enrofloxacin solution as model, to which hydrogen peroxide ...
