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].

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.

The process in Example 12-7 was conducted by initially adding 0.35 mol glucose to the 100-L reactor, and replenishing the reaction with 0.28 mol flesh glucose every 144 h for 30 days. Determine the gluconic acid and glucose concentration-time profiles in the reactor over this period...

In Fig. 4 it can be observed that the numerical simulations result in viability profiles qualitatively similar to the experiment. However in contrast to the experiment, in the simulations a considerable fraction of the cells in the center remains viable. In addition the critical glucose level fitted is very high, 4.5 x 10 3 //mol mm-3 compared to the initial glucose concentration of 5 x 10 3 Hmol mm-3.

Figure 19. 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.

Even for the fructose-glucose isomer system, with liquid phase concentrations that are an order of magnitude higher than those of the enantiomer system, the transport dispersive model is valid. Figure 6.32 shows that experimental and theoretical concentration profiles for a pulse experiment match very well using the isotherm data of Eq. 6.182. Eight semi-preparative columns were connected in series to...

Dimensionless degrees of freedom do not always transfer to other column designs as perfectly as shown in Fig. 7.1. In many cases some deviations in the concentration profiles have to be taken into account. These cases will now be demonstrated using a second exemplary separation problem the chromatographic separation of 1 1 mixture of glucose and fructose on ion-exchange resin Amberlite CR 1320 Ca from Rohm Haas (325 pm particle diameter) (Tab. 7.2).
