A thermodynamic investigation of the hydrolysis of sucrose to fructose and glucose has been performed using microcalorimetry and high-pressure liquid chromatography. The calorimetric measurements were carried out over the temperature range 298-316 K and in sodium acetate buffer (0.1 M, pH 5.65). Enthalpy and heat capacity changes were obtained for the hydrolysis of aqueous sucrose (process A): ...

The metabolic and energetic properties of Leuconostoc mesenteroides have been examined with the goal of better understanding the parameters which affect dextransucrase activity and hence allowing the development of strategies for improved dextransucrase production. Glucose and fructose support equivalent specific growth rates (0.6 h-1) under aerobic conditions, but glucose leads to a better bio...

Substrate and product inhibition of hydrogen production during sucrose fermentation by the extremely thermophilic bacterium Caldicellulosiruptor saccharolyticus was studied. The inhibition kinetics were analyzed with a noncompetitive, nonlinear inhibition model. Hydrogen was the most severe inhibitor when allowed to accumulate in the culture. Concentrations of 5-10 mM H(2) in the gas phase (ide...

The seeds of cereals represent an important sink for metabolites during the accumulation of storage products, and seeds are an essential component of human and animal nutrition. Understanding the metabolic interconversions (networks) underpinning storage product formation could provide the foundation for effective metabolic engineering of these primary nutritional sources. In this paper, we des...

The ability of an inulosucrase (IS) from Lactobacillus gasseri DSM 20604 to synthesize fructooligosaccharides (FOS) and maltosylfructosides (MFOS) in the presence of sucrose and sucrose-maltose mixtures was investigated after optimization of synthesis conditions, including enzyme concentration, temperature, pH, and reaction time. The maximum formation of FOS, which consist of β-2,1-linked fruct...

A comparative study was carried out on the dynamics of lipid accumulation in developing seeds of three lupine species. Lupine seeds differ in lipid content; yellow lupine (Lupinus luteus L.) seeds contain about 6%, white lupine (Lupinus albus L.) 7-14%, and Andean lupine (Lupinus mutabilis Sweet) about 20% of lipids by dry mass. Cotyledons from developing seeds were isolated and cultured in vit...

It has generally been accepted that the formation of granules in anaerobic wastewater treatment systems requires a hydraulic upflow pattern. To evaluate this hypothesis, we operated an anaerobic migrating blanket reactor (AMBR) without a hydraulic upflow pattern, using a synthetic wastewater containing acetate, propionate, butyrate and sucrose. We provided conditions amenable to the formation o...

possessing putative hypolipidemic effects, teucrium polium (tp) have been traditionally used as a medicinal plant in iran. the aim of the present study was to investigate this effect on the sucrose-induced insulin resistance male rat model. thirty wistar male rats weighting 180 ± 20 g were divided into five groups of six each. four groups were given sucrose 50% in drinking water for 10 weeks. i...

In the current study abilities for mixotrophic growth of phototropic cave strains were observed. The influence organic substrates on rate Chlorella vulgaris, Stichococcus bacillaris, Leptolyngbya foveolara, Scytonema studied. most cases glucose, maltose, glycerine, malate, acetate, sucrose, and peptone showed a stimulating effect culture by dark light incubation. Specific carbon consumption pro...
