Table 11-2 gives the results of the computer simulation and Ligure 11-17 shows the concentration profiles of the cell, gluconolactone, gluconic acid, and glucose with time. These profiles are in good agreement with the experimental data of Rai and Constantinides [14].

Feedback and GC mode SECM measurements of enzyme kinetics, (a) Feedback mode locally electrogenerated mediator is reduced by glucose ( ) at the substrate surface the reaction is catalyzed by glucose oxidase, (b) the GC mode the reduced form of the mediator is continuously produced by the enzyme-catalyzed reaction at the substrate and collected at the tip. The tip probes the concentration profile of reduced mediator species.

The separation of an industrial feed mixture of fructose-glucose (Cfeed = 300 g 1 ) containing 6% sucrose as an impurity is displayed in Figure 6.44. Once again, good agreement between experiment and simulation is found. The individual concentration profiles of this three-component mixture cannot be determined by two-detection systems. Therefore, additional samples (two per shifting interval) were taken and analyzed by HPLC.

A high glucose concentration of 150 g l 1 was used in continuous fermentation with immobilised S. cerevisiae the obtained data for sugar consumption and ethanol production with retention time are shown in Figure 8.13. As the retention time gradually increased the glucose concentration chopped, while the ethanol concentration profile showed an increase. The maximum ethanol concentration of 47 g l 1 was obtained with a retention time of 7 hours. The yield of ethanol production was approximately 38% compared with batch data, where only an 8% improvement was achieved.

Batch fermentations were carried out using rice bran and glucose as nitrogen and carbon sources, respectively. Figure 4 shows the profile of fumaric acid production in a 2.5-L jar fermentor. The fumaric acid concentration reached 25.3 g/L. The yield (fumaric acid produced/glucose consumed) and the productivity were 52% and 0.21 g/(L-h), respectively. For the following experiment, the fungal culture broth was used as a medium for the bioconversion of fumaric acid into succinic acid.
