A new consortium of four bacterial isolates (Agrobacterium radiobacter; Bacillus spp.; Sphingomonas paucimobilis, and Aeromonas hydrophila)-(CM-4) was used to degrade and to decolorize triphenylmethane dyes. All bacteria were isolated from activated sludge extracted from a wastewater treatment station of a dyeing industry plant. Individual bacterial isolates exhibited a remarkable color-removal...

In this work, the exploitation of synthesized magnesium oxide nanoparticles and MgO-bentonite nanocomposite as an effective photocatalyst has been reported. They were utilized to study their applicability for photocatalytic degradation crystal violet in wastewater. Fourier-transform infrared (FTIR) spectra, X-ray powder diffraction (XRPD), energy-dispersive spectroscopy (EDX), transmission elec...

The present study investigates the efficacy of AnvirzelTM, an extract of Nerium oleander, in more than 35 different human cancer cell lines, including all the types of tumours. Assays that have been used in order to measure the efficacy of AnvirzelTM in 24, 48 and 72h of incubation in 37 different cancer cell lines, were viability assays [Methyl-Tetrazolium dye (MTT), Crystal violet staining (C...

conclusions shiitake essential oil is an effective anti-bacterial and anti-biofilm agent on important oral pathogens and has a possible therapeutic potential as an oral anti-biofilm agent. results no inhibitory effect was observed on f. nucleatum biofilms (p > 0.05). significant disruptive properties on a. actinomycetemcomitans at values lower than the mic (3.90 µg/ml) was detected (p < 0.05). ...

Harrison Spectroscopy Laboratory, Massachusetts Institute of Technology, Cambridge, Massachusetts 02139 Department of Physics, Technical University of Berlin, D 10623 Berlin, Germany (Received 6 November 1996) By exploiting the extremely large effective cross sections (...

Magnetically modified activated carbon, which synthesized by nanomagnetic iron oxide, was used for fast and effective removal of Crystal Violet from aqueous solutions. The scanning electron microscopy (SEM) images of nano-adsorbent showed that the average sizes of adsorbent are less than 100 nm. The various parameters, affecting on adsorption process, were examined including pH and temperature ...

The synthesis, IR , P NMR and cyclic voltammetry characterizations of a new WellsDawson-type heteropolyanions which contains iron HFe2.5P2W18O62, 23H2O and HFe2.5P2W12Mo6O62, 22 H2O are reported. The catalytic activity of these compounds was evaluated through the oxidation of methyl violet dye, by hydrogen peroxide. The influence of different parameters such as the initial pH, the initial H2O2 ...

Aim: To evaluate the cytotoxicity of several storage media (coconut water, whole milk, isotonic solution, Hank ́s Balanced Salt Solution and tap water) using a multiparametric cytotoxicity analysis employing 3T3 cells. Methods: Plates containing confluent 3T3 fibroblasts were exposed to the various media for 24h, at 37°C with 5% CO2, and cell viability was evaluated by a multiparametric assay as...

Triphenylmethane (TPM) dye is one of the most prevalent and recalcitrant water contaminants. Magnetic reduced graphene oxide (rGO) is an efficient adsorbent for organic pollutants removal. However, the performance and adsorption kinetics of magnetic rGO towards TPM have not yet been studied. In this study, a magnetic Fe3O4@rGO nano-composite, which could be easily removed from water with a simp...
