Two distinct phases can be distinguished in the kinetic of release of reducing groups in order to study the regultion and synthesis of PG by the SCPP strain. Thus, we decided to estimate the effect of glucose on the PG activity at the start of the culture and define the cause of the stabilization phase in the release of the reducing groups... 

EFFECT OF GLUCOSE ON THE SYNTHESIS AND ENZYMATIC ACTIVITY OF POLYGALACTURONASE... 

In order to estimate the effect of glucose on the release of reducing groups in the culture medium, the SCPP strain has been inoculated on Pg glc media with glucose concentrations ranging from 0.1% to 1%. 

Figure 4 Effect of glucose on reducing groups release by SCPP Measurements were achieved after growing the strain in the presence of 1% polygalacturonic acid and varying concentrations of glucose. They were done on the culture supernatants as described by Milner et Avigad...

A crude protein extract has been prepared by acetone precipitation on a three days old culture supernatant of the SCPP strain on Pg glc medium. In order to estimate the effect of glucose on PG activity, these protein extracts were deposited as dots on solid Pg glc medium. 

PG induction levels are admittedly very weak. We would have been better off if we had taken the effect of glucose concentration on PG synthesis into account and had carried our experiment at a glucose concentration of 0.25%. 

Additionnally, we show that the PG activity of the SCPP strain is regulated. It is stimulated by polyglacturonic acid concentrations similar to the ones seen in various fruit juices. On an industrial point of view, this induction would be diminished by the elevated glucose concentrations found in these fruit juices when compared to the pectin concentrations. Basal activities would be sufficient to eliminate all pectins and obtain juice stabilization. It would also have been interesting to study the effect of glucose concentrations of 15% and 20% (concentrations found in fruit juices, beers and ciders) on the PG activity of the SCPP strain. 

Effect of Glucose to Glutamine Ratio on MAb Productivity in a Chemostat... 

At the Pharmaceutical Production Research Facility of the University of Calgary experimental data have been collected (Linardos, 1991) to investigate the effect of glucose to glutamine ratio on monoclonal antibody (anti-Lewish IgM) productivity in a chemostat and they are reproduced here in Tables 17.8, 17.9 and 17.10. Data are provided for a 5 1 (standard for cell culture media), 5 2 and 5 3 glucose to glutamine ratio in the feed. The dilution rate was kept constant at 0.45 d . 

Does the analysis of data suggest that there is a significant effect of glucose to glutamine ratio on MAb productivity ...

It has also been shown that LDL oxidation is increased in diabetes. In this connection, Mowri et al. [179] studied the effect of glucose on metal ion-dependent and -independent LDL oxidation. They found that pathophysiological glucose concentrations enhanced copper- and iron-induced LDL oxidation measured via the formation of conjugated dienes. In contrast, glucose had no effect on metal-independent free radical LDL oxidation. Correspondingly,...

Figure 16.3 Effects of insulin on the glucose/fatty acid cycle. Insulin enhances glucose metabolism by stimulating glucose uptake by muscle and adipose tissue and by inhibiting lipolysis in adipose tissue (see Chapter 12 for the mechanism of these effects). The effect of glucose metabolism on lipolysis is via stimulation of fatty acid esterification via glycerol 3-phosphate.
