Integral membrane proteins (IMPs) play crucial roles in all cells and represent attractive pharmacological targets. However, functional and structural studies of IMPs are hindered by their hydrophobic nature and the fact that they are generally unstable following extraction from their native membrane environment using detergents. Here we devise a general strategy for in vivo solubilization of I...

Phosphorus is one of the major components required for the metabolic activities and for the growth of any organism. Many soil organisms are known to solubilize inorganic phosphates. Aspergillus niger isolated from the soil showed extensive solubilization of Tri-calcium phosphate.It was observed that the solubilization was due to drop in pH.Acidification was due to production of organic acids by...

The solubilization of glucose and several related sugars in benzene solutions of rigorously purified phosphatidylcholine has been studied; the equilibrium degree of solubilization has been found to depend on the size of the sugar molecule relative to that of the lecithin micelle, and on the number and the acidity of its free hydroxyl groups. The uptake of glucose increased as the lecithin conce...

In this study, the solubilization of two organic dyes, Sudan I (1-Phenylazo-2-naphtol) and Quinizarin (1,4-Dihydroxyanthraquinone), was studied in the presence of different types of surfactants (2 polymerics, 2 nonionics, 2 anionic, and one cationic) using UV-Vis spectroscopy. The effects of temperature, pH and addition of different electrolytes (NaCl, Na2CO3, NaI, NaOH, NaSCN) on dye solubiliz...

Root nodulating bacteria was isolated from root nodules of Vigna trilobata (L) Verdc. Plants raised in the soils were collected from five geographically different areas in Andhra Pradesh, India. The bacteria was identified as Agrobacterium tumefaciens strains by 16S rDNA analysis. Except A. tumefaciens MRR 102, all the strains produced round shape and white coloured colonies with lot of mucilag...

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...

BACKGROUND Feedstock recalcitrance is the most important barrier impeding cost-effective production of cellulosic biofuels. Pioneer commercial cellulosic ethanol facilities employ thermochemical pretreatment and addition of fungal cellulase, reflecting the main research emphasis in the field. However, it has been suggested that it may be possible to process cellulosic biomass without thermochem...

the iranian thymus daenensis subsp. daenensis is rich in monoterpene phenols (especially thymol and carvacrol). this research was conducted to isolate and characterize the plant growth promoting rhizobacteria (pgprs) from rhizosphere of t. daenensis. pgprs were screened based on some physiological traits including iaa production, phosphate solubilization, and siderophore compounds production ab...

The dynamics of liposome solubilization was monitored by dynamic light scattering and optical microscopy. A newly designed Y-shape microchannel connected to a room was incorporated into a microchip and the reaction processes of the liposome suspension and surfactant solution were observed in the room after mixing the two fluids and stopping the flow. By using this microchip, we succeeded in r...
