A previously reported bacterial bioemulsifier, here termed microbactan, was further analyzed to characterize its lipid component, molecular weight, ionic character and toxicity, along with its bioemulsifying potential for hydrophobic substrates at a range of temperatures, salinities and pH values. Analyses showed that microbactan is a high molecular weight (700 kDa), non-ionic molecule. Gas chr...

Polyaromatic hydrocarbons (PAHs) with high molecular weight (more than three benzene rings) were difficult to degrade in saline environment. The present study details about the bacterial consortium enriched from industrial sludge from salt manufacturing company, Tuticorin, Tamilnadu (India), which was capable of degrading 1, 4 dioxane (Emerging micropollutant) and also phenanthrene as sole carb...

A new approach using fast atom bombardment combined with mass spectrometry to characterize polycyclic aromatic hydrocarbons (PAHs) in the range of 128-252 u molecular weight is described. Sulfolane was employed as a liquid matrix for these π-conjugated hydrocarbons. Bombardment of sulfolane solution of certain PAHs with an atom beam produces both radical cation (M(+.)) and protonated molecule [...

We propose a novel approach toward calculating activation and reaction volumes based on MD simulations of reaction systems. The accuracy of the calculated volumes, verified by the comparison to the experimental data, is suitable for quantitative analysis of the experimental volumes of activations in terms of structural parameters of the corresponding transition states.

conventional treatment of naja naja oxiana (nno) envenoming requires large volumes of equine antivenin raised against nno crude venom. the poor efficiency of this antivenin is assumed to be due to the high molecular weight non-toxic proteins, a strong immunogen, present in the crude venom. these proteins cause depression of antibody formation against the low molecular weight toxic components of...

In this paper, the ability of chrome shavings to remove motor oils, oily wastes and hydrocarbons from water has been studied. To determine amount of hydrocarbons sorbed on tanned wastes, a FT-NIR methodology was used and a multivariate calibration based on partial least squares (PLS) was employed for data treatment. The light density, porous tanned waste granules float on the surface of water a...

in this study, 120 aegilops crassa (mmdd genome) accessions from iran were evaluated for high molecular weight proteins. based on sds-page analysis, 17 bands were selected and mass spectrometry was used for protein identification. among 17 bands selected for maldi-tof-tof-ms analyzing, only 4 bands were identified as high molecular weight glutenin subunit similar to aegilops ventricosa and trit...

methods this randomized, crossover study with parallel design was conducted in 45 patients who required maintenance hemodialysis due to end-stage renal failure. four patients with known bleeding disorders, receiving anticoagulant drugs and receiving drugs which could affect heparin activity were excluded. all patients were randomly assigned to receive either enoxaparin sodium (0.7 mg/kg) or sta...
