BACKGROUND AND OBJECTIVES Azotobacter is a diazotroph bacterium reported to possess various plant growth-promoting characteristics.The aim of this study was to isolate Azotobacter strains capable of fixing nitrogen and effectively hydrolyzing both organic and inorganic Pi compounds. MATERIALS AND METHODS In this study, soil samples collected from a diverse range of slightly alkaline soil type...

BACKGROUND Strategies to improve copper-catalyzed alkaline hydrogen peroxide (Cu-AHP) pretreatment of hybrid poplar were investigated. These improvements included a combination of increasing hydrolysis yields, while simultaneously decreasing process inputs through (i) more efficient utilization of H2O2 and (ii) the addition of an alkaline extraction step prior to the metal-catalyzed AHP pretrea...

Three enzymes of intestinal origin-enterokinase, alkaline phosphatase, and sucrase-were released into the perfused small intestinal lumen of the rat upon intravenous injection of the gastrointestinal hormone cholecystokinin-pancreozymin (CCK-PZ). The presence of bile in the perfusion fluid greatly augmented this release. The results suggest that a combined mechanism of enzyme liberation due to ...

The action of non-detergent sulphobetaines (NDSBs) as new mild agents for protein purification is described. The solubilization effects of non-detergent sulphobetaines are shown in different examples; all obtained under non-denaturing conditions: (1) microsomal proteins extraction; (2) recovery after dialysis of nuclear proteins; (3) reduction of precipitation in isoelectric focusing experiment...

Abstract: In this paper, the use of surfactants for solubilization of. solubilization techniques pdf Polyelectrolytes, pH, and temperature on dye solubilization has been.Solution chemistry, solubility and solubilization. Dissolution limited bioavailability is a very c...

Pluronic/bile salt/phospholipid mixed micelles (Pluronic/BS/PS-MM) drug carrier system for solubilization hydrophobic drugs was developed. A typical hydrophobic compound, pyrene, was selected as a representative hydrophobic compound to model the hydrophobic drugs. Five Pluronics, F68, F88, F98, F108, and F127 with different PPO chain length were studied. CMC data and solubilization capacities w...

The by-product from tuna processing is a potential source of edible protein. Therefore, it is very important to extract protein from such raw materials for human food. In this study the optimum pH for protein extraction from tuna by-products was optimized by using isoelectric solubilization and precipitation processes. The Response Surface Methodology (RSM) and the single factor model were used...

enzymes is due to a more specific process than generalizedcell damage or loss (Holdsworth & Coleman, 1975). We have now attempted to make an initial separation of these enzymes from other biliary proteins, before investigating their relationship with the bile-canaliculus region of the hepatocyte plasma membrane. Fresh sheep bile was treated with solid protamine sulphate and centrifuged to remov...

The aim of this work was to study an innovative alkaline process on two cover crops. CaO load 60 g.kgTS−1 implemented combine the functions storage and pretreatment. Lab-scale reactors were monitored for 180 days assess effect physico-chemical properties biomass. From first days, pH not maintained in zone microbial fermentation activity observed with degradation available carbohydrates producti...
