In 1986, the FDA s Sugars Task Force assessed the impact of sugar consumption on human health and nutrition and concluded that sucrose is not an independent risk factor for heart disease, nor does it cause or contribute to the development of diabetes (62). Although diet is important after the onset of diabetes, sucrose can be well tolerated by insulin-dependent diabetics (63—65).

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 reaction rate for simple fermentation systems is normally given by the Monod equation. This model indicates that the specific conversion rate is constant when applied to an immobilised cell system (Table 8.7). If a first-order rate equation for sugar consumption is used, (8.7.4.2) yields ...

Hint if you aerate a bioreactor, die power consumption is less than a non-aerated bioreactor and the specific sugar consumption rate is 1 kg-kg 1 cell h-1. 

Recent experiments from our laboratory93 show that the same general principle holds with respect to sugar consumption. Rats on nutritionally deficient diets, when given a choice, consume more sugar than those which have their nutritional needs better satisfied. 

The design of safe sweeteners is very important for people who are afiected by diabetes, hyperlipemia, caries and other diseases that are linked to sugar consumption. Sweet proteins, which are found in several tropical plants, are many times (100-100,000) sweeter than sucrose on a molar basis. Only a few sweet proteins are known miraculin, monellin, thaumatin, curculin, mabinlin. 

Dental caries is one of the most common diseases in humans, and is mediated by bacteria, mainly Streptococcus mutans. It has been estimated to affect between 60 and 90% of school children in the developed world and the majority of adults [11], and is consequently a major public health concern. In addition to the developed world, it is the most widespread oral disease in many Asian and Latin American countries, though it currently appears to be less of a problem in Africa. However, changes in living conditions and increases in sugar consumption within a changing diet suggest that, in Africa too, the incidence of caries will increase, and that it will become a major public health issue here, too.

Louis Pasteur found that aeration increases biomass production and decreases the kinetics of sugar consumption and ethanol production (Pasteur 1861). He, therefore, concluded that aeration inhibits alcoholic fermentation (Packer 1974).
