Rare metal (La or Nd) doped BaSn-based composites with highly polycrystalline nature were successfully synthesized through a simple hydrothermal route. The investigated by X-ray diffraction, electron microscopy, solid ultraviolet diffuse reflectance spectrum, photoelectron spectroscopy, photoluminescence, electrochemical impedance and photocatalytic measurements. La Nd doping induces the morpho...

The development of thin-film composite membranes has gained more importance as they exhibit higher permeability, solute rejection and improved antifouling behavior. incorporation hydrophilic nanomaterials within the thin film reported to effectively increase hydrophilicity improve membrane performance. In this study novel nanofiltration were prepared by interfacial polymerization trimesoyl chlo...

Ninety-nine selected compounds and eleven antibiotic-producing organisms were tested for antiphage activity and host toxicity. A paper disc-agar diffusion method was used for primary screening and quantitative methods were employed for confirmatory investigation. Most of the agents tested, although previously reported as inhibitory to one or more other virus-host systems, did not selectively pr...

This paper analyzes the adsorption of two potential toxic dyes, i.e. methylene blue (MB) and crystal violet (CV) onto Bauhinia forficata residual fruit powder (BFRFP) as a new promising adsorbent. The experiments aimed at retrievement data are carried out T = 298–328 K coupled with an adsorbent characterization to better highlight MB CV dyes mechanism. capacity saturation (ACS) varies from 181....

Plasmid pGNB1 was isolated from bacteria residing in the activated sludge compartment of a wastewater treatment plant by using a transformation-based approach. This 60-kb plasmid confers resistance to the triphenylmethane dye crystal violet and enables its host bacterium to decolorize crystal violet. Partial sequencing of pGNB1 revealed that its backbone is very similar to that of previously se...

Several papers have been published (Kennedy and Barbaro, 1953; Barbaro and Kennedy, 1954; Bartholomew and Finkelstein, 1954; Kennedy and Woodhour, 1956; Barbaro et al., 1956) on methods of comparing degrees of gram-positiveness and the influence of certain factors on the quantity of crystal violet retained by the microorganisms. These papers compare the degrees of gram-positiveness by measuring...

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 Yersinia pestis, Y. pseudotuberculosis, and Y. enterocolitica, phenotypic expression of virulence plasmid (pYV: 70-kb)-associated genetic determinants may include low-calcium response (Lcr, pinpoint colony, size = 0.36 mm), colony morphology (size = 1.13 mm), crystal violet (CV) binding (dark-violet colony), Congo Red (CR) uptake (red pinpoint colony, size = 0.36 mm), autoagglutination (AA =...

27 The enzyme triphenylmethane reductase (TMR) reduces toxic triphenylmethane dyes into 28 colorless, non-toxic derivatives, and TMR-producing microorganisms have been proposed as 29 bioremediation tools. Analysis of the genome of Listeria monocytogenes H7858 (1998-1999 hot 30 dog outbreak) revealed that the plasmid (pLM80) of this strain harboring a gene cassette 31 (bcrABC) conferring resista...

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). ...
