BACKGROUND An ideal immobilized biocatalyst for the industrial-scale production of invert sugar should stably operate at elevated temperatures (60-70°C) and high sucrose concentrations (above 60%, w/v). Commercial invertase from the yeast Saccharomyces cerevisiae is thermolabile and suffers from substrate inhibition. Thermotoga maritima β-fructosidase (BfrA) is the most thermoactive and thermos...

Sugarcane is a crop valued mainly for the high sucrose content in its cane stalks. Since sucrose is the most essential part of commercial cane sugar (CCS), it automatically becomes the top priority for farmers, and consequently, for breeders and agronomists as well. In the mature internodes, sucrose content can reach around 25% of the fresh weight of the culm. However, the rapid inversion and d...

in this research we have studied tabriz temperature inversion using radio-sound information, during the 2004-2008 periods in daily, monthly and seasonally scales. produced data associated with temperature inversion daily of the surface (2 meters) to 700 h.pa. several different measures are used, including the height of the base and the height of the top of the inversion, the temperature at the ...

In the hydro-thermally prepared title compound, [Mo(8)Zn(2)O(26)(C(8)H(7)N(3))(4)](n) or {[Zn(C(8)H(7)N(3))(2)](2)(Mo(8)O(26))}(n), the Zn(II) atom is coordinated by two N,N'-bidentate 3-(2-pyrid-yl)pyrazole ligands and two O atoms from adjacent octa-molybdate polyanions, generating a distorted cis-ZnO(2)N(4) octa-hedral geometry for the divalent metal ion. The complete octa-molbydate unit is g...

Effects of exogenously applied methyl jasmonate (MeJA) and sucrose on vase life and non-structural carbohydrate concentration in petals and leaves of cut ‘First Red’ roses were investigated. Roses were placed in sealed plastic containers and received MeJA vapour treatment (0.1 μL MeJA L-1) for 24 h at 20°C. Flowers were then placed in individual bottles containing 0 or 2% (v/v) sucrose solution...

In an investigation of the minor sugars of honey at this laboratory, examination by paper chromatography indicated that several oligosaccharides are present. These have not yet been identified. Since honey is the product of the reaction of honeybee (1) invertase with nectar sugars [sucrose, glucose, and fructose (2)], a comparison is being made of the sugars of honey with the oligosaccharides p...

generally, the measured secondary field data is inverted into resistivity using two principal models; the homogeneous half-space model and the layered half-space model. while the homogeneous half-space inversion uses single frequency data, the inversion is done individually for each of the frequencies used, the multi-layer 1d inversion is able to take the data of all frequencies available into ...
