Two bacterial species; Pseudomonas fluorescens and Pseudomonas putida and three different chemical compounds; copper sulphate (CuSO4), Indole butyric acid (IBA) and potassium chloride (KCl) were tested for their ability to induce resistance in lupine plants against wilt disease caused by Fusarium oxysporum f. sp. lupini. Treatment of seeds with the selected bacterial species and chemical compou...

the thermal denaturation of α-amylase from bacillus amyloliquefaciens has been investigated in the presence and absence of sodium dodecyl sulphate (sds) over the temperature range (293-373) k in 20 mm sodium phosphate buffer, ph 6.9, using temperature scanning spectroscopy. the presence of sds caused the destabilization of α-amylase resulting in a decrease in the temperature of unfolding with a...

Further evidence has been obtained which confirms that foot-and-mouth disease virus contains several structural proteins. By electrophoresis in urea-polyaerylamide gels, virus of type O gave six distinct bands. In sodium dodecyl sulphatepolyacrylamide gels four proteins with molecular weights of 34, 3o, 26 and Iy5 x io 3 were clearly demonstrated. When virus preparations were labelled with a si...

This work demonstrates a novel method for the synthesis of large pore mesoporous silica nanoparticles (MSNs) with a pore diameter of 10.3 nm and a particle diameter of ∼50 nm based on the incorporation of mixed anionic surfactants sodium dodecyl benzene sulfonate (SDBS) and sodium dodecyl sulphate (SDS) as the template in the synthesis process. The dispersity, morphology, pore structure and siz...

Silver (Ag) nanoparticles were successfully prepared by using the in-liquid pulsed plasma technique. This method is based on a low voltage, spark discharge in dielectric liquid. We explore effect of protecting ligands, specifically Cetyl Trimethylammonium Bromide (CTAB), Polyvinylpyrrolidone (PVP), and Sodium n-Dodecyl Sulphate (SDS), used as surfactant materials to prevent nanoparticle aggrega...

Abstract By-products and wastes generated by the oil gas industry must be properly managed treated. Oil-drilling cuttings (ODCs) are major during process of oil/gas exploration extraction. ODCsispre-treated in a sonicator mixing it with synthetic seawater pre-specified composition at varying volume ratios, presence anionic surfactant sodium dodecyl sulphate (SDS) various concentrations (0%, 0.2...

The binding of Sodium n-dodecyl sulphate (SDS) to histone H3 was studied in the pH range 3.2-10 by equilibrium dialysis at 27? and 3 7 ?c .T he binding data have been used to obtain the Gibbs free energy of interaction using a theoretical model of the Wyman binding potential; and the enthalpy of interaction from the temperature dependence of theequilibriumconstantsfronr theVan't Hoff re1ati...

Three different high-performance liquid chromatographic (HPLC) techniques, i.e. affinity, ion exchange, and gel filtration chromatography, have been used to purify polyclonal antibodies from bovine serum. Polyclonal antibodies were obtained from animals infected with bovine leukaemia virus, which was confirmed by AGID and ELISA tests. Precipitation of the antibodies by ammonium sulphate prior t...
