Sucrose hydrolysis was carried Out by Saccharomyces strains. The effective rate of reaction was examined experimentally for 5 different Saccharomyces strains. Two Strains of Schizosaccharomyces and Saccharomyces Carlsbergensis showed the best invertase activity. These two strains showed Michaelien Kinetics in the sucrose concentration up to 0.2 M and inhibitory effect in the concentration b...

OBJECTIVE Although sucrose is considered the most cariogenic carbohydrate in the human diet, the question of how many exposures are needed to induce damage on the hard dental tissues remains unclear. To approach this question, different frequencies of daily sucrose exposure were tested on a relevant biological caries model. MATERIALS AND METHODS Biofilms of the Streptococcus mutans were forme...

Figlewicz DP, Bennett JL, Aliakbari S, Zavosh A, Sipols AJ. Insulin acts at different CNS sites to decrease acute sucrose intake and sucrose self-administration in rats. Am J Physiol Regul Integr Comp Physiol 295: R388–R394, 2008. First published June 4, 2008; doi:10.1152/ajpregu.90334.2008.—Findings from our laboratory and others have demonstrated that the hormone insulin has chronic effects w...

The aim of the work was the modification of a carbon nanotube paste electrode with a highly original osmium-polymer hydrogel for the development of a new amperometric biosensor for detection of sucrose and fructose. The biosensor for sucrose is based on the activity of the enzymes invertase and fructose dehydrogenase (FDH) immobilized into a carbon nanotube paste (CNTP) electrode properly modif...

The preference of female Sprague-Dawley rats for sucralose, a non-nutritive sweetener derived from sucrose, was evaluated in 23 h two-bottle tests with water or saccharin. Overall, the rats displayed weak or no preferences for sucralose (0.25-4 g/l) over water but strong preferences for saccharin (0.5-8 g/l) over water and saccharin (1 g/l) over sucralose (0.5 g/l). The rats also preferred a sa...

Posttrial administration of corticosterone was previously shown to enhance consummatory successive negative contrast (cSNC) in rats. The present series of experiments provides additional information that helps determine the boundaries of this effect. Posttrial corticosterone administration (1) enhances cSNC when rats experience a large downshift (32% to 4% sucrose), but not after a small downsh...

Prior work has shown that sweet taste-deficient T1R3 knockout (KO) mice developed significant sucrose preferences when given long-term sugar versus water tests. The current study investigated the role of olfaction in this experience-conditioned sucrose preference. T1R3 KO and C57BL/6 wild-type (WT) mice were given 24-h sugar versus water tests with ascending concentrations of sucrose (0.5-32%),...

the use of isomalt and maltitol instead of sucrose in foods has an important role in human health as controlling blood glucose levels and weight management. in this study, isomalt and maltitol instead of sucrose were used at three concentration level (75, 85, and 100%). effects of the polyols were investigated on physicochemical properties (size of bubble cake batter, moisture content, water ac...

The aim of this study was to determine the effects of different plant growth regulators, NAA (0 mg/l, 50 mg/l and 100 mg/l) and GA3 (0 mg/l, 50 mg/l and 100 mg/l), with various boron concentrations (0 mg/l, 50 mg/l and 100 mg/l) on pollen germination of ‘Şaba’, ‘Rabie’ and ‘Padre’ almond cultivars in 10% sucrose and 1% agar medium at 24°C in dark conditions. The results showed that different tr...
